2. Matching Section Baseline
Warm Powering per IP side:
1 x HCRPHRA R2E-LHC4-6-8kA+08V for Q4 (LS2)
1 x HCRPHSB R2E-LHC4-6-8kA+08V for Q5 (LS2)
1 x HCRPHSB R2E-LHC4-6-8kA+08V for Q6 (LS2)
16 x ​HCRPLBC R2E-HL-LHC120A-10V needed to power:
Q4 correctors : 8 MCBY
Q5 correctors : 6 MCBY
Q6 correctors : 2 MCBC

4. SAVINGS / Descope Estimation
Implications for WP6B
Warm Powering per IP side:
Q4-Q5-Q6 No changes
Q4-Q5-Q6 correctors go down from 16 to 10
Warm Powering for the whole HL-LHC
-24 units of HCRPLBC R2E-HL-LHC120A-10V to be installed
-2 spare units of HCRPLBC R2E-HL-LHC120A-10V
SAVINGS / Descope Estimation
HL : 24 x 26 kCHF = 624 kCHF
HL-CONS: 2 x 21 kCHF = 42 kCHF
TOTAL (on 6B.6 budget being formalized): 666 kCHF
