Components controlled over DCS • • • HV LV – Dual. Sampa, SOLAR crates Temperature Dual Sampa – config SOLAR – config CRU MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 7

HV • No change in HV plan in the upgrade scenario • DCS: system-wise same as the present system • Trip handling may evolve – e. g. automatic HV adjustment on overcurrent MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 8

LV • Supply SOLAR and DS – new configuration in the upgrade scenario • DCS: system-wise analogous to the present system (MANU → DS; CROCUS → SOLAR) Numbers will change – depending on the LV segmentation MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 9

Temperature Monitor temperature at the chamber level – same as present system MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 10

Dual Sampa 16828 DS boards I 2 C protocol over fiber, GBT, ribbon, flex • Some form of separation for DS 12 and DS 345 • Configuration – globally, Solar/crate/chamber/station-wise (option/s to be decided) MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 11

SOLAR 624 SOLAR boards • GBT Configuration – globally, single/crate/chamber/station-wise (option/s to be decided) • Reset – globally, single/crate/chamber/station-wise (option/s to be decided) MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 12

CRU 30 CRU • Configuration – FW reprogramming (? ) • Append DCS info to data packets at specific intervals - tbd • Monitoring? MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 13

O 2 req ID • Data to be tagged with unique id • ID available – DS, SOLAR, CRU • Sufficient to have an unique ID which is unique in a Station MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 15

O 2 req Configuration tool • We need a tool in order to configure the whole readout chain • Analogous to LC 2 where we can add/remove FEE components at any level we want – DS/Solar/Crate… to be decided • This tool should decode the same config file used by DCS to configure the chain Should be considered also in the processing requirements of O 2 in the FLP level MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 16

O 2 req: Commissioning One CRU has 24 bidilinks for optical fibers • station 1: work by quadrant, need 12 links = 1 CRU • station 2: work by quadrant, need 12 links = 1 CRU • station 3: work by half-chamber, need 26 links ==> 2 CRU • station 4: work by half-chamber, need 38 links ==> 2 CRU • station 5: work by half-chamber, need 44 links ==> 2 CRU Commissioning Station 1(quadrant): 1 CRU - 1 FLP Station 2(quadrant): 1 CRU - 1 FLP Stations 3, 4, 5(half-chamber): 2 CRUs – 1 FLPs Total: 4 CRUs, 3 FLPs MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M.

MCH O requirements 2 Processing needs in the FLP Estimation of the processing power to analyze the data once stored in the FLP memory. …. . FLP availability for commissioning at P 2 Number of FLP and CRU/GBT links needed to commission the detector (at P 2 or in another lab). Commissioning will be independently done for Station 1, Station 2 and Station 345 The requirements for commissioning at P 2 (without spares) are as follows: - 1 CRU for commissioning of quadrants station 1: 1 FLP - 1 CRU for commissioning of quadrants station 2: 1 FLP - 2 CRU for commissioning of half-chambers of stations 3, 4, 5 : 1 FLP Total: 4 CRU and 3 FLP for commissioning in the Cavern ( the CRU/FLP should be installed in the cavern for commissioning) In addition we need 2 set ups for laboratory tests at CERN (one already existing with GRORC). For that we need 2 CRU and 2 FLPs in total for the two setups. Starting date when the infrastructure must be ready to start such a commissioning We will start the commissioning in the cavern not before March 2019. In the lab we would like to have the set up by mid/late 2018 if possible. MCH Upgrade DCS (+O 2) Requirements | 07 Nov 2017 | M. Arba 19
