General info: Andre will be back in Heidelberg in 2 weeks
round table:
Heiko:
- Mupix10 Wafers arrived on mondey, in total 11 - they are allready picked by Luigi, Heiko, Benni.
- Already some
- 3 Wafers were picked by some guys from buchum which took the Sensors to Bochum
Sebastian:
- Had a look for solutions for the fpga bords: new Sellers found (Elustra: FPGA on small boards, not expencive, Arria10 for 500$) - need to have a closer look because there are many options/choices
- The Idea of having a base board and a additional fpga board is interesseing as the fpga can be exchanged easily
- Lars sets up a Arria5 Setup at PSI - incontact with Thomas and Dohun
Alena:
- Presentation: Measurement with Sr90 with HitCounting Chip
- Not yet more comparisons between the normal and the ISOHit version (Iso has a slightly lower breakdown voltage)
- Chips are not thinned - effects on efficiency
- Andre: Any plans for run2021: not all chips are working yet so no conglusion but the hitcounting chips work good so the will be prob. continued
Annie:
- working with the data of the run2020 testbeam
- problems in the code: right now she sees a efficiency is at ~80% (similar to the result from lennard)
- Compaire the code with data of Mupi10 where the efficieny of 99% is allready known.
- Andre: dealing with Atlaspix1 papre draft: should be annies work included? Annie sent some of her results to Adrian already but its not clear what should be used.
Benni:
- Busy with picking run2020 and Mupix10 sensors
- start looking into pcb design of the frontend card from Alex
- Problem with the connectoron the new pcb: was found on the loop-back card: the support strucktur of connector could not fully be placed on the board, leading to some population problems - should not occur on the frontend card. This should be checked with Frank Schuhmacher - was already checked with Dirk
Dohun:
- Works on the Arria5 setup - at first it seems to work but now there are Problems and it does not work anymore
- Will continue to look into this the upcoming week
- Questions: if no sensor is connected normaly 8/10bit errors can be seen in the nios but for this setup this is not true - Sebastian: when no chip is connected it is not quarantied what happens because the input is floating - should not care about that
- Problem with the setup: The chip worked in the first day and is still working on Florians setup - now the sensor can not be configured anymore - when the problem was first seen nothing was changed on the setup, since then the scasi cable, trancseiver card was exchanged, fpga firmware was reloaded
- Test with the new Arria5 and with Mupix8 - if this is not working a meeting should be arranged
Florian:
- Designed a prototyp for the tile case - found already some changes which has to be done
Konstantin:
Marius:
- The plan for the upcoming weeks should be made
Thomas:
- arranged a meeting with the companie for the cabeling
- Are we sticking to micro twisted pair or can they present their products? (they have some own version with a teflon cable inside) - stability is not a crucial feature
- one should asked them aboud impedance and if they have ideas how to optimise the impedance of the whole setup
- A first Mupix10 is already clued on a HDI, have to be bonded - first: check if its working, then define for what the HDI should be used - do we have to order more HDIs?
Luigi:
- Probcard investigasion: still now results, still problems - a new probcard will be populated with less needles (probcard light)
- worked on the Datebase
- LTU is makeing the plan for next year - they need a lot Kapton 25um 35m2- will be send to them by us via gsu
coll meeting next week - Luigi should organise an update also from the uk side
