Ronic Chiche | Fixed | info | lasers and optics | detectors and electronics | software | ThomX igloo | restarting CFP system after the long summer shutdown (RF section conditionning) and Alphanov amplifier issue | now, the Ring RF frequency is set to 500.067MHz.
so the CFP/laser frequency should
be 500.067MHz/15 = 33.3378MHz. |
