CARE-SRF : Cold Piezo Tuner<br />
New design of cold tuner<br />
The preload on the piezos is defined by the cavity<br />
compression strength, therefore by the cavity frequency<br />
tuning:<br />
1 - before chemical treatment (field flatness)<br />
2 - pre tuning before cooling<br />
Rough estimation on the uncertainty of the preload<br />
value at cold from 300 N to 2000 N<br />
(« optimum » preload for the piezo NOLIAC ~ 600N)<br />
⇒ Need to optimize the frequency tuning<br />
⇒ Integrated Cavity Tests in CRYHOLAB<br />
