CTRL cablesCTRL cables
Simplest/safest solution seems to have a small custom made fast signal repeater betwen 2x25m cables:
Then, the CTRL board can stay in the same crate as the TELL1s (50m from BGV).
Did a similar thing in the PS booster (VELO zap test)
CTRL cables needed length: 8x2x25m = 400m – available from CERN stores, now, 900m
– scem 04.21.44.180.6, 5.2 CHF/m => 2.1 kCHF
– same connectors as for data signal cables

DAQ/nw/storage Milestones ?DAQ/nw/storage Milestones ?
define event size and rate – data format and occupancy and noise
– different types: NZS, full ZS, nano...
define dimensions of switch/farm/storage set up test bench at Pt8 develop (copy) software
– event builder

– data writer
– ctrl&mon DAQ system ready for installation at Pt4

Event sizeEvent size
Data format
– 27 = 128 channels => nch bits , nch = 7
– cluster finding in TELL1: 2 thresholds, Tseed is seed threshold, and Tincl is the inclusion threshold for neighbour channels.
– take highest ADC and add up to Nnbr neighbour ADCs
– ADC bits = nADC . How many ? Check resolution. nADC = 6 OK ?
Example 1: Lite Clusters
– Cluster position bits: ncl = nch + ninter = 7 + 3 = 10 (within a Beetle)
– nB = bits to encode which Beetle, say nB = 7 (128 Beetles)
– Absolute space position: ncl + nB = 17 bits
Example 2: Full Clusters
– «Channels per cluster» bits: ncpc = 3 (max 8 channels per cluster)
– Cluster position bits: ncl = nch (first cluster channel)
– nB = bits to encode which Beetle, say nB = 7 (128 Beetles)
– Cluster data size: ncpc + nch + ncpc nADC + nB = 3 + 7 + (1...8) 6 + 7 = 23...65 bits

data ratedata rate
DAQ must cope with
Input data rate given by:– 8 Tell1’s, fully loaded (128 Beetle chips)
ZS data LiteClusters+FullClusters at full rate (1MHz), all Tell1’s:
(UTC + BCID + (17 + 23...65) bits/cl * xx cl/evt ) * 106 evt/s = ~600 Mb/s
Supersparified NZS: add 16384*10bits at tunable low rate (prescaling)
Output rate:– about 1 evt/s per bunch and up to 2500 bunches => max 2500 evt/s
– sum of three rate types: full rate: vertex position and cov matrix (12 floats ?), BCID, cl and track multiplicities (3
integers) => ~60 bytes / evt => 150 kB/s
sparsified: full clusters => (UTC + BCID + 35 bits/cl * xx cl/evt ) * 103 evt/s = ~ 60 kB/s
supersparsified: NZS data => (UTC + BCID + 16384 * 10 bits) * 100 evt/s = ~ 20 kB/s
xx = 10 ?UTC = 64 bits ?BCID = 12 bits
xx = 10 ?UTC = 64 bits ?BCID = 12 bits
