Outline

• 35T Power

• “Simple” scale of power to CERN single phase prototype (may be room for optimization)

Rack Services – Rack Protection System (D. Huffman)

Consists of two parts—chassis and smoke sensor (SS 2W-B)

•Economical solution (~$650)

•Design includes:

–System Sensor photoelectric smoke sensor.

–EPO (Emergency Power Off for UPS).

–+12V Voltage output interlock.

–Two sets of NO/NC interlock contacts, AUX1 and AUX2.

–Audible alarm.

–Front panel reset button.

–Status bit to Slow Controls.

35T HV Drift Rack

RACK Powered from one 120V/20A SurgeX: SX-1120-RT

Same equipment can be used for CERN Prototype Installation

35T Trig_Scint Rack

RACK Powered from one 120V/20A SurgeX: SX-1120-RT

Questions: Do we have sufficient coverage with present 35T counters for CERN prototype?Will present equipment be reliable for CERN Proto and do we have spares?

35T TPC_PD Rack

7/30/2015 T. Shaw | Neutrino Platform Meeting10

RACK Powered from two 120V/20A SurgeX: SX-1120-RT

For CERN Prototype we anticipate upgrades:Photon Detectors plan will gang SiPM readout (groups of 3) and require:

qty(15) 16-channel SSP (Silicon Photo-multiplier Signal Processor) Readout Modules (present SSPs are 12-channel)

Required Pulser/Calibration units for CERN Prototype:qty (2) Pulsers for Photon Detectors – similar to SSP unitsqty (8) Pulsers for FE modules

Weiner MPOD Crate for HV Wire Bias Will be very similar to 35T

Weiner MPOD Crate for FE LVRight now a full 10 slot MPOD crate is being used to supply 5

independent voltage channels to each FE card. If we stay with this design, we will need 9 MPOD crates to supply LV for 6 APA’s FE modules.

35T Purity Monitor Rack

7/30/2015 T. Shaw | Neutrino Platform Meeting11

RACK Powered from two 120V/20A SurgeX: SX-1120-RT

For CERN Prototype, some type of purity monitor will be required.In the process of checking with cryostat team.

35T Camera Rack

7/30/2015 T. Shaw | Neutrino Platform Meeting12

RACK Powered from one 120V/20A SurgeX: SX-1120-RT

35T has a set of 9 Cameras inside cryostat.

35T DAQ Racks (2)

Each rack powered by one Eaton:PW309BA0U409 208/3φ/30Aand one 120V/20A SurgeX: SX-1120-RT

Mostly similar equipment list, but we will need to have two ATCA shelves to support a quantity of 15 COB readout boards.

DAQ racks to be enclosed air conditioned racks.
