WG1 Task2 New structures, new designs, new geometries P. Colas 19/02/2009 RD51 - WG1 status report

Digging in new ideas New materials (resistive for various applications, meshes, transparent conductors, etc…) New structures (double grid, MHSP for backflow suppression, µPIC+mesh) New « details » : hole size, rims Welcome to newcomer from VECC Kolkata 19/02/2009 RD51 - WG1 status report

R & D with GEMs and THGEMs at VECC, Kolkata Anand Kumar Dubey (for the VECC Group, S. Chattopadhyay et al.) Compact Baryonic Matter muon chambers main issues: -- The first plane(s) has a high density of tracks detector should be able to cope up high rate. ~ 10 MHz/cm2 -- good position resolution -- Should be radiation resistant -- Large area detector – modular arrangement --Should be cost effective (INDIA GOOD AT THIS) suitable option  micropattern gas detectors GEMs, THGEM, micromegas ALSO medical imaging

Exploring all these possibilities is very promissing for many applications. Example: make a detector faster by cutting out the ion tail (using the RC circuit as a filter) 19/02/2009 RD51 - WG1 status report

Ion gating with a double-mesh device Ed = 0.2 kV/cm Et = 2 kV/cm Ea = 50 kV/cm Aim : gate the ion drift lines escaping the amplification gap Transparency depends on the field ratio 16th june 2009 Fabien Jeanneau 3rd RD51 meeting, Kolympari, Crete, Greece

IBF Achievements with MHSP and COBRA Achievements with the F-R-MHSP shows IBF level needed for visible sensitive GPM. Also with COBRA, but this one with limited collection efficiency. MHSP COBRA or COBRA IBF close to 10-4 Full ECE IBF 1000 x lower than with GEMs At the expense of ECE (20%) A. Lyashenko et al., NIMA 598(2008)116 A. Lyashenko et al., NIMA JINST(2009), in press 04/09/2018 Kolympary, 11-18 of June 2009 RD51

Thick-MHSP Structure – large areas In order to apply the same principle, it was produced a new Thick-structure with the goal of reduce IBF in cascade Thick-structures. Same principle of Thick-GEM production.... -Cathodes “strips” with a circular shape surrounding the holes; -holes (0.3 mm diameter with a 0.1 mm rim), are placed in an hexagonal lattice with a pitch of 1.0 mm; -anodes (0.3 mm wide), running between each pair of cathodes. 04/09/2018 Kolympary, 11-18 of June 2009 RD51

Thick-MHSP Before starting IBF studies we have polarized the structure like in a MHSP standard operation. Polarization scheme similar to MHSP MHSP Thick-MHSP 04/09/2018 Kolympary, 11-18 of June 2009 RD51

Both, experimental and simulation results are in course GAIN Good gas gains, good single photon detection. More studies are needed for better understanding the avalanche development and the resulting gain increase when polarizing the extra electrode. IBF GPMs operating in Thick-GEM cascades: semitransparent or reflective PCs. Experimental studies of: - IBF, - collection efficiency and; - gain. Using the Th-structure in reverse mode or flipped reverse mode are in course. Preliminary simulation studies indicates that good IBF reduction could be possible. Depending on the results for IBF, this structure will allow to increase the lifetime of this photodetectors in the same order of magnitude as the out-coming results for the IBF reduction. 04/09/2018 Kolympary, 11-18 of June 2009 RD51
