1 Jan Uythoven For discussion
LHC TL and Sector test meeting 9/10/2014 BETS tests for MSI, TDI and TCDQ Jan Uythoven For discussion

2 Beam Energy Tracking System
BETS already existed during Run I on beam dumping system Main Bends, 4 sectors MKD, MKB and MSD (dump and dilution kickers, dump septum) Q4 quadrupole L/R 6 Run II: add similar system on MSI (injection septum) RMSI power converter has become an LHC type pc  ramp down These functions need to be defined as well together with OP, including degauss cycle to be applied TDI (Injection absorber) TCDQ (dump absorber) See also MPP meeting 19/7/2013: LHC TL & Sector tests, 9/10/2014 Jan Uythoven

3 BETS transfer function for MSI
Change of transfer function to be done locally in the tunnel Transfer function to be checked by MCS Arming sequence for BETS on MSI not needed (standalone) LHC TL & Sector tests, 9/10/2014 Jan Uythoven

4 BETS on MSI Description Proposed procedure / actions:
Works on absolute current Maskable interlock, connected to injection BIC Proposed tolerance 7 rad  1 sigma oscillation = 5e-4 tolerance on the MSI current Proposed procedure / actions: Preparation: Contact EPC and ask for current stability measurements (Hugues Thiesen) Set BETS transfer function to +/- 5e-4 relative error (Nicolas Voumard) Check we have rights to move the MSI current outside the above window MCS rights & trim rights Test: Close Injection BIS loop with MSI at nominal current. Move current of MSI outside tolerance window both ways and check each time the BETS stops injection permit Change BETSIM to 452 GeV and check injection BETS stops injection permit Check if MCS reference not correct, cannot arm injection BIS LHC TL & Sector tests, 9/10/2014 Jan Uythoven

5 BETS transfer function for TDI
Change of transfer function to be done locally in the tunnel Transfer function to be checked by MCS Arming sequence for BETS on TDI not needed (standalone) LHC TL & Sector tests, 9/10/2014 Jan Uythoven

6 BETS on TDI Description Proposed procedure / actions:
Works on gap between the two jaws To start with LVDT, 2016 on interferometry if all goes well Maskable interlock, connected to injection BIC Proposed tolerance ±1 sigma, about ± 0.6 mm Proposed procedure / actions: Preparation: Check stability of LVDT / interferometry gap measurement Set new BETS interlock window +/- 0.6 mm (Nicolas Voumard) Check energy limit used (+/- 1 GeV) Check we have rights to move the TDI (collimator role & MCS for BETS) Test: Close Injection BIS loop with TDI at nominal position. Move current TDI position outside tolerance window by moving first one jaw and then repeat with other jaw, check each time the BETS stops injection permit Set BETSIM to 452 GeV and check one cannot inject Check if MCS reference not correct, cannot arm injection BIS LHC TL & Sector tests, 9/10/2014 Jan Uythoven

7 TCDQ transfer function
Change of transfer function to be done locally in the tunnel Transfer function to be placed in MCS BETS on TCDQ needed during the arming sequence of the LBDS LHC TL & Sector tests, 9/10/2014 Jan Uythoven

8 BETS on TCDQ Description Proposed procedure / actions:
Works on absolute position of upstream and downstream side of jaw To start with LVDT, 2016 on interferometry Maskable interlock to BIS in point 6 Proposed tolerance ±1 sigma, about ± 0.XXX mm  to be determined Proposed procedure / actions: Preparation: Check stability position readings up and downstream Set new BETS interlock function +/- 0.XXX mm around ‘random’ reference function for up and downstream position (Nicolas Voumard) Check we have rights to move the TCDQ (collimator role & MCS for BETS) Test: At injection energy move TCDQ upstream outside tolerance window and check that interlock is generated. Repeat for downstream part of jaw. Repeat for both jaws at 6.5 TeV beam energy (real or BETSIM) Modify TCDQ ramp function so that requested position of one jaw is 2 x tolerance at 3 TeV, perform energy ramp (with nominal machine if available or with BETSIM) and check interlock is generated. Check if MCS reference not correct, cannot close BIS LHC TL & Sector tests, 9/10/2014 Jan Uythoven
