6. HVCMOS pixels
HV/HR-DMAPS activities at IFAE started in the framework of ATLAS
HV/HR-DAMPS features:
Sensors + electronics on the same device and fabricated with standard CMOS technologies
Thick depletion region: ~ 100µm
Fast collecting time: ~1ns
Radiation hard
Large fill factor (electronics over the sensor)
Thinning and back side biasing

7. HVCMOS pixels
HV/HR-DMAPS technology is being investigated for applications beyond HEP:
Thick depletion region Soft X-ray detection/Near IR
Back Side Illumination Higher quantum efficiency
CMOS technology + monolithic device economical competitive
IFAE’s activities on HVCMOS pixels beyond ATLAS:
Development of MONOPC_LF ASIC: first HVCMOS chip for soft X-ray detection
Joining efforts with other institutions. Interest of ALBA in this technology.
First prototype will be delivered in March and characterized at IFAE
AIDA-2020 proposal rejected in final stage, Producte proposal under evaluation

8. Light Trap for Gamma Ray Astronomy
project led by John E. Ward (D. Guberman, J. Cortina)
basic idea: detect light with “large” WLS disk and guide it to small SiPM coupled to disk
aim: replace expensive PMTs of a Cherenkov telescope by much cheaper light sensor
Project was started around 2 years ago as Marie Curie project + SO Seed Funds
Additional funds from MPI Munich
Thorsten Lux

9. ... And possibly beyond
currently developing SiPM readout for cluster of 7 light traps
mechanical structure also under construction
installation in Magic camera in May 2017
Interested in use electronics for other applications:
we had similar idea for WA105
larger disk, about 20 cm diameter
PMMA disk coated with TPB on top
2nd WLS fiber around disk read by 1 or 2 SiPMs
Intensive MC study by PhD student
still planned to do tests

11. Ultrasound for Underground Searches
Ultrasound used for medical imaging
Could it be used for imaging of underground objects?
Idea by Matteo Cavalli-Sforza
Tested together with Mokhtar at Parc Tauli Hospital in Sabadell
Nov We presented a "Llavor" proposal about 20 kEuro. Yes/no answer in 1-2 months from now. - Just now we presented BIST-ignite proposal for 20 k€, in collab. with Gustau Catalan (ICREA, ICN2). Focus on understanding ultrasound attenuation mechanisms in soil and and optimization of frequency range

13. 3D Screen Printing of MPGDs
Lead by T.L.
Thick Micro-Pattern-Gas-Detectors (MPGDs) interesting for several experiments as DUNE or DHCAL
Current production process based on drilling holes
hundred thousand holes per m2
1 m2 of THGEM takes about 50 hours
900 m2 for one DUNE detector: ~5 years
more complicated geometries even more time consuming/ not possible
idea to use 3D screen printing instead
small tolerances of 10 m possible
much faster and much cheaper
completely new concepts might be possible
AIDA-2020 proposal submitted but also rejected in final stage
Thorsten Lux

14. 3D Screen Printing of MPGDs
Collaboration of Fraunhofer Institute, Weizmann Institute and IFAE producing first prototype
Funds from SO Seed money for this (10 kEuro)
Production until June including several quality tests
Crucial is the hole quality
Tests in gas detector also at IFAE also foreseen
Investigating in parallel possibility to submit FET-Open proposal in September 2017

15. Future Accelerator Project

17. Summary Number of instrumentation “side” projects increasing
Much more people and groups are working on these
SO Seed money very helpful to start
Efforts are undertaken from the beginning to find external funding
Some already achieved external funds: High-T-Sc, Asteroid, light trap, ...
... and several proposals under evaluation currently
Help to do networking with other institutes
New lab spaces hopefully will also help to work more on these projects
