Equipment Status

1
Equipment Status

• ARCS equipment status
• Single module and 4 hybrid
• DAQ equipment status
• Vienna box, Single rod, Multi-rod
• Needed Spares
• Mostly power supplies

2
ARCS equipment-modules (UCSB)

• UCSB need 1 DEPP and 1 LED board for 3rd module
  stand
• Should ship next week (LED system 2 months away)
• UCSB also needs to rotate the 3 ARCS controllers
  here with 3 with new firmware
• Otherwise, false problems found
• Bad MUX in fast test
• High noise channels in noise
• Low injection channels in Pinhole/Cal Injection
  Test
• Should ship next week
• DEPP boards all inject noise into system
• Sending 3 TOB modules to Aachen for DEPP debug
• Need to use Keithley until problem fixed
• New order of Keithley needed

3
ARCS equipment-hybrids (UCSB)

• UCSB 4 hybrid thermal cycler functional
• Critical equipment (spares)
• Old ARCS controllers (Correct trigger stuffing)
• No old spares, but new ARCS boards maybe stuffed
  correctly
• NIM components
• Spares of all modules in-hand
• A spare NIM crate would be good
• Peltier Power Supply
• Need to order spare from CERN Electrics Pool
• Peltier element
• In hand
• Coolie Box
• 1 spare in US in hand by next week

4
ARCS equipment-modules (FNAL)

• All 4 stands fully operational
• Use DEPP boards- Do you see same problem?
• Which version of firmware in ARCS controllers?
• With new firmware delay between clock and ARC ADC
  clock 2-3 ns
• With old firmware delay closer to 7-8 ns
• Need to send back all ARCS controllers with old
  firmware for upgrade
• Are DEPP boards injecting noise into system?
• Causes higher noise in opens and sensor edges
• 2 Keithley HV supplies on site sufficient back up

5
ARCS equipment-hybrids (FNAL)

• 4 hybrid thermal cycler functional
• Critical equipment (spares)
• Old ARCS controllers (Correct trigger stuffing)
• Lenny indicate FNAL has at least one additional
  old controllers
• NIM components
• Spares of all modules and crate in-hand
• Peltier Power Supply
• Need to order spare from CERN Electrics Pool
• Peltier element
• Did we order this???
• Coolie Box
• 1 spare in US by next week

6
ARCS equipment-hybrids (Mexico)

• 4 hybrid thermal cycler in assembly
• All ARCS equipment in hand next week
• Critical equipment (spares)
• Old ARCS controllers (Correct trigger stuffing)
• No spares on site, will have to be sent by
  UCSB/FNAL
• NIM components
• Spares of all modules in-hand
• NEED NIM CRATE SPARE
• Peltier Power Supply
• Need to order supply spare from CERN Electrics
  Pool
• Peltier element
• Need to order spare

7
Vienna Box (FNAL UCSB)

• Both Vienna Boxes operational
• UCSB Peltier power supply is having switching
  problem (see below)
• Enough adapter boards in-hand to make second set
  of cold plates
• UCSB needs 10 TEC adapter boards for cold box
• Should be delivered next week
• Critical equipment
• All spare DAQ equipment in hand except
• No spares for eMUX components
• Will order 1 spare set of each component as US
  spare pool
• TPO
• Can take from single rod stand if needed (Will
  need 3 FED per single rod stand w/o TPO)

8
Vienna Box (FNAL UCSB)

• Critical equipment
• Peltier power supply
• Both sites have had fuse housing melt and UCSB
  supply is not switching correctly
• Ordered spare power supply per site (Delivery in
  2 months)
• LV Power supply
• UCSB had high current Leader power supply
  overheat, replaced with Agilent PS for single
  rods
• Need to order spare Agilent PS (E3633A) for each
  site
• Should I do this?

9
Rod Test Stands

• All DAQ equipment in hand except for
• TPO-like object
• Both multi-rod stands need this spares
• No idea when this will arrive
• Electrometer
• No clear if we will ever get this
• Should we try to find acceptable multi-channel
  nano-anameter
• Need to run stands to see weak points
• Potential problems
• DELPHI PS failures
• MUX failures
• oFED/oFEC failure
• Not clear if spares are sufficient (or if we even
  have all we need) until stands operational

10
Total Equipment Needed (Not Already En-route)

• 3 NIM Crates
• 4 Peltier PS
• 2 Peltier Elements
• At least 4 TPO-like objects
• 2 Agilent E3633A PS
• At least 1 Keithley PS
• 4 Electrometers (or equivalent)
• eMUX spares
