6 Test of the first MPGD-based (S)DHCAL

Digital and Semi-Digital Hadronic Calorimeters (S-DHCAL) were suggested for future Colliders as part of the particle-flow concept. Though studied mostly with RPCs, MPGD-based sampling elements could significantly improve the calorimeter performance thanks to their proportional response.

In 2018, several large-area resistive Micromegas and Resistive Plate WELL (RPWELL) of 48x48$~$cm$^{2}$ were tested at CERN. The performance of the first produced detectors were studied with high energy particles delivered by the SPS machine. Then, all detectors were grouped with steel absorber plates into a small MPGD-based SDHCAL prototype which recorded hadronic showers of low-energy pions from the PS.

The response of the individual sampling elements and of the calorimeter will be reported. For the former, emphasis will be put on MIP efficiency and hit multiplicity, spatial uniformity, HV stability, and rate effects. The calorimeter response is derived from data samples recorded at different pion momenta, from 2 to 6 GeV/c. To minimise leakage at the rear of the calorimeter, pions showering in the first layers were selected. This way, the energy resolution of the prototype could be assessed as well. Results will be shown and when possible, compared to simulated ones.

37 Low-pressure TPC with THGEM readout for ion identification in Accelerator Mass Spectrometry

A new technique for ion identification in Accelerator Mass Spectrometry (AMS) has been proposed based on measuring the ion track ranges using a low-pressure time projection chamber (TPC). As a proof of principle, the low-pressure TPC with charge readout using a THGEM multiplier was developed. The tracks of alpha-particles from various radioactive sources were successfully recorded in the TPC. The track ranges were measured with a rather high accuracy, reaching 3%. Using these results and SRIM code simulation, it is shown that the isobaric boron and beryllium ions can be effectively separated at the 10 sigma level. This technique is expected to be applied in the AMS facility in Novosibirsk for dating geological objects, in particular for geochronology of Cenozoic Era.

41 ACTAR TPC: a tool for nuclear physics applications

The ACTAR TPC (Active Target & Time Projection Chamber) is a detector developed for fundamental nuclear physics studies such as nuclear reaction and structure studies as well as exotic decay and proton emission studies. It results from the joint efforts to build a second generation gaseous target and detector that merges the advantages of the first generation active target MAYA based on wire amplification and the CENBG TPC based on GEMs.

In addition to specific developments concerning the high density collection plane (with 16k pads) and the active volume, the device is equipped with the GET electronics that allows for time sampling of signal of each pad for a full 3D reconstruction of tracks. The pad planes are equipped with 128 and 256 µm bulk micromegas (64x128 mm2) either on standard PCB or on a specific metal-core PCD. After the realization of demonstrator detectors that have been tested in various conditions including in beam tests, the final detectors (2 pad plane geometries have been designed) are now almost completed, with in-beam commissioning runs at GANIL, for active target and decay detector modes of the device.

We propose to present the characteristics of the detector in terms of particle tracking and energy analysis, resulting from the various source and beam test measurements. We will also address the issues related to the gas used in Active Targets.

The ACTAR TPC device is planned to be used in 2 experiments at GANIL in 2019.

42 GEM detectors for the MAGIX focal plane: minimising materials for low energy experiments

The new MAGIX experiment, to be built at the 105 MeV line of the ERL MESA at the institute for Nuclear Physics of the University of Mainz, features two high-resolution spectrometers looking at the target area where luminosity of the order of $10^{35} \text{cm}^{-2}\text{s}^{-1}$ will be achievable. To improve the momentum and angular resolution of the spectrometers, the greatest challenge is to minimise the material budget of their GEM-based focal plane detectors as much as possible.
In this talk we will present the solutions we developed to build a high-resolution MPGD tracker for those experimental conditions including a foil based readout plane with Chromium-GEM amplification and a short-drift TPC with an open field cage, the latter being the solution finally approved for the experiment.

43 new MPGD-based structures for electroluminescence TPCs

Optical TPCs, specially those operating in electroluminescence mode, are widely used in the searches for rare events, particularly in those involving the reconstruction of very faint energy deposits (down to single photon/electron sensitivity) or outstanding energy resolution.

Unlike avalanche multiplication, electroluminescence depends just on the maximum voltage that the structure can sustain, hence thick structures are preferable. In order to work in these conditions, a new type of very thick GEM ('FAT'-GEM) based on acrylic has been developed at CERN workshop. Acrylic is a rugged and homogeneous radio-pure material, easy to machine and widely available, therefore it holds some promise for a new generation of optimised structures in the field of rare event searches. First measurements under an Ar/Xe mixture at 10bar already showed an energy resolution extrapolating to 2%(FWHM) for the Qbb-energy of 136Xe, at an optical gain of around 1000ph/e. We will report in this contribution results of this ongoing effort, presenting results for a wide range of structures, gases and pressures.

48 Development of high-performance DLC resistive electrodes for MPGDs

Diamond-like carbon (DLC) films are a class of metastable amorphous low-dimensional materials characterized by a mixture of diamond-structure with sp3 type C bonds and graphite-structure with sp2 type C bonds at the atomic level. DLC films open up new avenues to make high-performance resistive electrodes for Micro-Pattern Gaseous Detectors (MPGDs) that present numerous attractive properties, such as excellent mechanical performance, chemical inertness, thermal stability and a large range of electrical resistivity. The DLC resistive electrode not only replace the traditional carbon paste resistive electrode made by screen printing technique to avoid the occurrence of spark between electrodes, but also allow to develop new MPGD structures. In recent research, we have developed a thin DLC film on APICAL substrate with unbalanced magnetron sputtering technology. The sputtering process has been optimized with regards to mechanical adhesion, internal stress and surface resistivity of the DLC coating. A systematical study of the factors affecting the DLC surface resistivity have been investigated, including target power, deposition time, vacuum degree, element doping, and annealing treatment. The results are summarized as follows: (1) the surface resistivity decreases with the increase of the target power and the sputtering time, and appears more stable and uniform at lower target power (0.55kw) with longer sputtering time (40min); (2) the vacuum degree during the sputtering has a significant impact on the surface resistivity: the higher the degree of vacuum, the lower the surface resistivity; (3) hydrogen doping can increase the surface resistivity, probably due to the increase of the sp3 component in the DLC film; (4) after the annealing treatment at 200 degree, the surface resistance decreases to about 1/3 of its original value and stays stable afterwards. We also briefly present several examples of application of the DLC coating in development of MPGDs, including DLC photocathodes for the Picosecond Micromegas detector, resistive DLC electrodes for the μRWELL detector, and high-resistivity DLC coating for “charging-up free” THGEM detectors.
In conclusion, we have developed a manufacturing technique for high-quality DLC resistive electrodes for MPGDs as a result of interdisciplinary research involving both material science and particle physics. Development of DLC resistive electrodes opens up enormous opportunities for innovative development and application of MPGDs.
