Thermal test(lab modules)

G. Riddone, A. SamoshkinLast update 25-Jul-2011

Complement to the presentation on 14.06.2011

Thermal tests

• Investigation of the thermo-mechanical behaviour of the module following:– Variation of the ambient temperature– Variation of the RF structure temperature

(PETS and accelerating structures)– Variation of the DB Quadrupole

temperature• Validation of the FEA model by

comparing results with simulated values

2

Measurements

• Measurement of temperatures and comparison to simulations BE-RF

• Measurement of deformations/stresses and comparison to simulation EN-MME (K. Artoos) + BE-RF

• Measurement of the RF structure alignment Method to be defined by SU

Possibility to use IR camera to be investigated

Planning

• Accelerating structure and PETS being assembled several steps and learning process

• QDB and BPM are available• The aim is to complete the assembly

of the first module by end of 2011– Afterwards thermal tests can start
