3 mCBM 2024

• FEE CROB
• new FEE
• beamtime schedule

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

GSI beam time 2024

Hi All, 

it was found the CROBs should not be operated at 12 V supply voltage, but with 7.5 V. 

Reason is not only to enable SCA usage, but also to avoid a risk of damage. Was found and investigated by Walter, see 
https://git.cbm.gsi.de/walters-test-environment/dca-prototype/-/issues/40#note_29505 

Also in contact with SCA designers, he assumes a risk of high ageing/damaging of the ADCs in the SCA with 12 V at the CROB input. 

@Alex, Claudiu: As far as I remember, the TRD-2D uses the LV supply channels mixed for CROBs and other FEE, right? Nevertheless, maybe lowered voltages can be realised. Please let me know when any MPOD channels can/shall be changed in this regard. 

@All: TRD-1D CROBs in mCBM are changed to 7.5 V already. Please consider the new voltage recommandation also in your lab setups. 

Best 
Philipp
