Turko, Joseph Lutz, Benjamin Meric, Ilker Müller, Sara Tabea Ratliff, Hunter Römer, Katja Ellen Urban, Konstantin Kögler, Toni 2025-06-24 This data set contains the experimental raw data from the measurement campaign at PTB in March 2024 funded by the European Innovation Council (EIC). Setup: The miniNOVO prototype (version 4) consists of 14 organic scintillator elements (7 × M600 and 7 × organic glas scintillator) of the dimensions \(12 × 12 × 140~\text{mm}³\). The scintillator bars have dual readout composed of 2 × Hamamatsu R7378A (1’’) PMTs1, 4 × Hamamatsu S14161-3050HS-04 SiPM1 + U3012 (+ custom front-end electronics) and 8 × Hamamatsu R2059-01 (2’’) PMTs1. The data was recorded with 2 CAEN V1730S3 14-bit, 16-channel digitizers (named dta and dtb) with a sampling frequency of 500 MS/s. A 1’’ CeBr3-detector was employed as a reference detector and positioned centrally behind the array. This detector was used for time calibration and time-of-flight measurements as start detector with a Pu-238 source. The detector array was irradiated head-on with mono-energetic neutron fields at the PIAF accelerator facility (Tandetron accelerator) of the energies \(E_n = \{ 1.2, 2.5, 6.5, 14.8, 17.0, 19.0\}~\text{MeV}\). The array position was shifted in two dimensions in 1 cm increments for the \(14.8~\text{MeV}\) measurements, in 5cm increments for \(17.0~\text{MeV}\) and at 1, 2 and 5 cm in both directions for the remaining energies. Data structure: The directory calibration contains six subdirectories dedicated to the time calibration with the reference detector, the position calibration with a Sr-90 source, the energy calibration with a Bi-207 and a Na-22 source, the gate optimisation and the gain matching. In the neutron_beam folder the measurements with the different neutron fields can be found, sorted into the corresponding subdirectory by energy. Waveform data recorded with a Pu-238 source is saved in the waveform_data folder and measurements with the reference detector can be found in the reference_detector directory. All other measurements and test runs are stored in the tests folder. influxDB holds the slow control data entries in a csv file and the main configuration files for the digitizers are saved in the DDAQconfig folder. In documentation a pdf-file of the elog providing more detailed information about the individual data files and a pdf-file with the detector setup are stored. Data Format: All data is saved in root files which each contain two root trees, one for each digitizer, named “dta” and “dtb”. The trees hold the following information in the form of listmode data for each event: digitizer channel ("channel"), charge integrated over long gate ("Elong"), charge integrated over short gate ("Eshort"), digitizer flags ("flags") and the timestamp (separated in three parts: "timestamp", "timestampExtended", "time"). Additionally, the root files also contain an TArrayD which denotes the start time of the measurement in UNIX time at its first index and the stop time at its second. There are two configuration files for each data file (named “filename_dtx.config”), one for each digitizer card. These text files contain the information about the digitizer settings for each run.

García Rivas, Iris Fernández Prieto, Antonio Kögler, Toni Römer, Katja Hueso González, Fernando 2024-04-16 This repository contains raw experimental data acquired during the gELBE beam time performed in October 2023 under proposal number 23203137-ST, at Helmholtz-Zentrum Dresden - Rossendorf. In this setup, a bremsstrahlung beam of up to 12.5 MeV energy in 13 MHz pulses irradiates a CeBr3 scintillation detector (by Hilger®) of Ø 1'' x 1'', coupled to a Hamamatsu® R13408-100 PMT, custom voltage divider and shaping electronics, and a commercial digitizer (SFMC01+SIS1160) by Struck®, containing an AD9689 chip that supports a data sampling rate of 2.5 Gsps and 14-bits. This detector is developed in the context of the coaxial prompt gamma-ray monitoring method [1], where very high count rates are expected [2]. The dead-time-free data acquisition is programmed in-house using ROOT [3]. In addition, a plastic scintillation detector (paddle) was placed inbetween the beam and the CeBr3 crystal to serve as reference beam monitor. An Arduino is used to monitor the high-voltage supply for the PMT and active divider electronics in terms of current, voltage and temperature. A Comet Systems® T7310 is used to monitor ambient temperature, humidity and pressure. The published data consist of the raw signal waveforms acquired during ~450 measurements. Each measurement is stored in a separate folder, its name being the acquisition time start, and lasts between 3 and 20 seconds (16 GiB up to 100 GiB). The data format is little-endian binary. Each sample uses two bytes, being the 14 first bits the digitized signal in a 1.7 Vpp range, and the 15th bit the (negated) logic status of the reference beam monitor (paddle). Samples are stored consecutively, without headers. Sample time separation is 0.4 ns (2.5 Gsps). The digitizer is phase-locked to the accelerator radiofrequency (RF), so that each 2500 stored samples correspond to 13 consecutive periods of 13 MHz. The data can be directly opened using the open-source pulse visualization software (PulseSurfer) available in this link: https://igit.ific.uv.es/ferhue/pulse-surfer/, with ROOT as a dependency. One just needs to run: root -l test_gui.cpp+(\"/path-to-folder/chA.bin\") and then set 192.307692307692307696 in the "Cycle" box. Use the slider in the bottom to navigate across different consecutive frames. To visualize the paddle counter (negated) logic status, change the "Mask" box from 3FFF to 4000. There is also a checkbox to activate the baseline subtraction. In addition to the raw waveform data (chA.bin), each folder contains following metadata: log.root a ROOT file storing all the measurement and hardware settings as TObjString. It also contains the T7310 monitoring as a TTree ("pth") chA.root a ROOT file storing a TTree that benchmarks the readout speed of the DAQ for this channel zdt.log a text file storing the output printed by the DAQ software to terminal gui.png Screenshot of the DAQ window hv.txt a test file storing the monitoring of the high-voltage supply and electronics This activity has received funding from the European Union's 2020 research and innovation programme under grant agreement No 101008126, corresponding to the RADNEXT project.

Göthel, Ilja Bernert, Constantin Bussmann, Michael Garten, Marco Miethlinger, Thomas Rehwald, Martin Zeil, Karl Ziegler, Tim Cowan, Thomas E. Schramm, Ulrich Kluge, Thomas 2022-01-31 In the effort of achieving high-energetic ion beams from the interaction of ultrashort laser pulses with a plasma, volumetric acceleration mechanisms beyond Target Normal Sheath Acceleration have gained attention. A relativisticly intense laser can turn a near critical density plasma slowly transparent, facilitating a synchronized acceleration of ions at the moving relativistic critical density front. While simulations promise extremely high ion energies in in this regime, the challenge resides in the realization of a synchronized movement of the ultra-relativistic laser pulse ($a_0\gtrsim 30$) driven reflective relativistic electron front and the fastest ions, which imposes a narrow parameter range on the laser and plasma parameters. We present an analytic model for the relevant processes, confirmed by a broad parameter simulation study in 1D- and 3D-geometry. By tayloring the pulse length and plasma density profile at the front side, we can optimize the proton acceleration performance and extend the regions in parameter space of efficient ion acceleration at the relativistic relativistic density surface. https://rodare.hzdr.de/record/1199 10.14278/rodare.1199 oai:rodare.hzdr.de:1199 url:https://www.hzdr.de/publications/Publ-33204 doi:10.14278/rodare.1198 url:https://rodare.hzdr.de/communities/fwk url:https://rodare.hzdr.de/communities/matter url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode Software for "Optimized laser ion acceleration at the relativistic critical density surface" info:eu-repo/semantics/other software

Wrobel, Nico 2023-01-06 The submitted version of my bachelor thesis. Abstract The accessibility of plasma-based accelerators was greatly expanded by the realization of laser wakefield accelerator (LWFA)-driven plasma wakefield accelerators (PWFA). This development speeds up research on PWFA significantly. In this thesis, 3D particle-in-cell-simulations were used to analyze driver parameters for a PWFA to achieve maximal energy gain for a hypothetical witness beam. Only small increases in witness energy were found when drivers with high kinetic energy were compared. In contrast, great witness energy increases result when the divergence of the driver gets reduced. The transformation of a driver in plasma is analyzed, and the influence of the wakefield on it is discussed. Additionally, evidence for non-constant peak energy is presented, with energy losses in the MeV scale independent from driver characteristics. This could require adjustments to the charge reconstruction of the LWFA bunch after the PWFA stage. https://rodare.hzdr.de/record/2128 10.14278/rodare.2128 oai:rodare.hzdr.de:2128 eng url:https://www.hzdr.de/publications/Publ-36490 doi:10.14278/rodare.2127 url:https://rodare.hzdr.de/communities/fwk url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode PWFA, PIConGPU, Plasma Accelerator Studying the impact of electron bunch characteristics on plasma wakefield performance using particle-in-cell simulations info:eu-repo/semantics/other other

Wrobel, Nico 2023-01-06 The submitted version of my bachelor thesis + tex files and notebooks used for data evaluation. Abstract The accessibility of plasma-based accelerators was greatly expanded by the realization of laser wakefield accelerator (LWFA)-driven plasma wakefield accelerators (PWFA). This development speeds up research on PWFA significantly. In this thesis, 3D particle-in-cell-simulations were used to analyze driver parameters for a PWFA to achieve maximal energy gain for a hypothetical witness beam. Only small increases in witness energy were found when drivers with high kinetic energy were compared. In contrast, great witness energy increases result when the divergence of the driver gets reduced. The transformation of a driver in plasma is analyzed, and the influence of the wakefield on it is discussed. Additionally, evidence for non-constant peak energy is presented, with energy losses in the MeV scale independent from driver characteristics. This could require adjustments to the charge reconstruction of the LWFA bunch after the PWFA stage. https://rodare.hzdr.de/record/2144 10.14278/rodare.2144 oai:rodare.hzdr.de:2144 eng url:https://www.hzdr.de/publications/Publ-36490 doi:10.14278/rodare.2127 url:https://rodare.hzdr.de/communities/fwk url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode PWFA PIConGPU Plasma Accelerator Studying the impact of electron bunch characteristics on plasma wakefield performance using particle-in-cell simulations info:eu-repo/semantics/other other
