DUNE Cryo Instrumentation & Slow Controls Joint Consortium meeting 20/10/2017 Some compilation on slow controls & instrumentation racks A. Cervera IFIC - (CSIC & Univ. Valencia)
2 Introduction • This is just a collection of thoughts: • Presentation from J. Fowler (March) • DocDB document by T. Shaw (June) • Some input from G. Lehman and X. Pons (CERN) • Some initial understanding of the slow controls and instrumentation needs
3 Needs • Instrumentation: • Temperature sensors: 500-1000 . • Purity monitors: 6 • Cameras: 12 • Level meters and pressure sensors: ? • Slow controls • APA/PD HV and electronics • CPA HV • Field cage HV • Ground planes impedance • Heaters, etc • Hardware interlocks
4 Thoughts from March https://indico.fnal.gov/getFile.py/access?contribId=52&sessionId=4&resId=7&materialId=slides&confId=13923

7 racks • At that point we were considering something like this: slow controls and instrumentation racks
8 Terry’s thoughts • Exercise done by Theresa Shaw few months ago https://docs.dunescience.org:440/cgi-bin/ShowDocument?docid=4499 • Two options: • Single rack (APA wires, PDs and DAQ) for 2 APAs • Three racks for 6 APAs, separating wires, PD and DAQ • As far as Grounding and Shielding, she thinks it would be great if we could move most or all of the DAQ hardware into the CUC Control room where there is a dedicated set of 48+ Racks

10 Option 1 • 1 rack for two APAs, everything together • slow controls: • one 1U slot for DCS controller (X. Pons suggests two slots) • one 1U for ethernet switch
11 Option 2 • 3 racks for 6 APAs, splitting wire readout, PD readout and DAQ • Terry thinks it would be good to move the DAQ hardware into the CUC • Slow controls: • one 1U slot for DCS controller in each rack (X. Pons suggests two slots) • one 1U slot for ethernet switch in each rack
12 Instrumentation • Cryogenics and LAr Instrumentation is not included in the previous scheme but the needs are quite modest: • 42 multiplexing cards for 1000 temperature sensors • The issue here is how to distribute them to minimise the cable lengths and the number of ADC modules for readout 6U size multiplexing card for • 2 half racks for purity monitors, at the two far ends 24 temperature sensors • 12 cameras are foreseen, I don’t know how much space they need, but I don’t think this will be a problem
