2 mCBM preparation

-status of FEB production / test

Speakers: Claudiu Schiaua (IFIN-HH/DFH), Alexandru Bercuci (IFIN-HH)

Tactica

• -> 15.01 - primele 3 cartelele de test ajung in DFH
  • ??? - in functie de rezultatul testului David & Christian & TRD1D primesc OK-ul pentru scoaterea TRD2D din cave si depozitare
  • ??? - upgrade infrastructura cave (HV, Optic fibers)  (DE, CS & PK, FR) 
• -> ??.02 - toate cartelele testate in DFH si gata pentru transport
• -> 21.02 -> 28.02 - montare FEB si instalare TRD2D in mCBM
  • 22.02 - 24.02 - SIS 12C -> 18O. Cave inchis dar pot exista ferestre ! Asemenea pentru 28.02, SIS 18O -> 197Au. 
• -> 28.02 - teste locale, debug
• -> 29.02 - primul fascicol de Au pt mCBM, teste (locale)
• -> 4.03 - 8.03 - CM
• -> 18.03 - al doilea fascicol de Au pt mCBM (probabil)

Hi Alex, 

our planning is based so far on ISEG EHS 305 20p as listed here 
https://iseg-hv.com/de/products/detail/EHS 

i.e. 48 channels positive per module, up to 2 kV (!), up to 1.5 mA per channel, common floating ground. 

An offer is attached, the abovementioned modules can be seen in position 8. Additionally, for the drift wires, position 9 for negative voltage up to (!) -500 V. 

Planning is: one channel (of each polarity) per chamber. Which was suiting the anode current calculations, but should still be confirmed with mCBM reality. 

Up to 10 of those modules can be operated in the crate as in position 1, each equipped with a "CC24" controller as in position 2. 

Prices of the single positions in the offer are without tax. 

--> Unfortunate situation is, that BMBF is granting so far only money for HV supply of the "german" chambers. I do only report that situation, but can neither defend nor directly influence it. We shall check in detail later, if anything can be covered still. 

To my understanding, all TRD HV has to be based on same technology. The suggested crates and "CC24" controllers do offer native EPICS. 

Best regards 
Philipp
