  1. EDMS №: [Number] CLIC MODULE Procedure for the thermal and alignment testing of CLIC duty cycles Written by: Elena Daskalaki Checked by: Alexander Samochkine Approved by: GermanaRiddone

  2. Contents Scope Thermal tests setup Thermal measurements Operating conditions Outcomes Duty cycles Nominal operation mode Failure mode Planning *Input and help from: N. Gazis, F. Rossi, I. Kossyvakis

  3. Scope The aim of the thermal tests is to investigate the response of the CLIC module with respect to temperature and alignment when operation-equivalent thermal power is applied.

  4. Thermal tests setup

  5. Thermal measurements *Ref: I. Kossyvakis, R. Mondello. Thermal Test Program For Clic Prototype Module Type 0 (EDMS No: 1304240)

  6. Operating conditions

  7. Outcomes • Thermal measurements • DBQ • PETS • RFN-Loads • AS • AS-Loads • Alignment measurements • DBQ • PETS • AS • Correlation of alignment to the temperature change ΔΤ • Time constant of DBQ, PETS, AS Steady state and transients Steady state and transients Temperature stability condition: ± 0.3 oC

  8. Duty cycles • Nominal operation mode • Powering of the DB-Quads • Unloaded Conditions • Loaded Conditions • Transient modes during nominal operation • Transition sequence 1  2 • Transition sequence 2  3 • Transition sequence 3  2 • Transition sequence 2  1 • Transition sequence 3  2  3 • Transition sequence 3  1  2  3 • Potential failure scenarios: 4 cases • Global CLIC failure • MB is shutdown • DB and MB are shutdown • Module failures • Accelerating Structure breakdown • PETS breakdown *Ref: N. Gazis. Thermal test simulation of the duty cycles (CMWG 18 Sep. 2013)
