lastDAC ROC temperature readout

• lastDAC is a part of analog readout. If we want,
  we could use it to readout temperature for the
  chip with a hit.
• Where should we store it ?
• A) Oracle DB
  ?
• ?
  need online script
• B) Keep it
  in the RAW data?
• How about to compress the info into 1 byte and
  keep it in the RAW data at least during the
  Engineering Run ?

5
DCU readout

• We need to readout temperature and voltage
  through DCU.
• FPix group has no experience.
• Strip Tracker group has experience (F Drouhins
  talk).
• ? FPix group needs help !!!

6
Common Issues

• How is the panels looks like for strip tracker
  DCS ?
• ? FPix panel should look similar
• How Strip Tracker group handle BARREL ENDCAP
  issues ?

7
DCS Hardware Issues

• Do we need to AOH temperature monitor - control ?
• ? AOH is known to be very senstive
  to temp
• Are we absolutely confident of overpressure
  cooling ?
• ? even small amount of leak could be
  really bad
