Today we do XRays for experiment.

The laser start to 33% at 93 KW but Pgain = 0.033

The laser is locked so stable for the moment. We have Xrays and the system is stable.

I have started a trend of laser power.

Some high freq perturbations are visibles but no delock.

It's clear that when the charge vary a lot in the ring we see more high frq perturbations!!

Each time we inject electrons we see high freq pert!!! But the delock are rare!

When electrons are lost we see high freq perturbations!!

New PID parameters

P=0.03

I=0.0005

I2=0

D=0.5

Axe18=+0.0016014

We have done a vertical scan and de e-beam seem to be very very large!! >1mm

The e-beam is not well adjusted but the lock is really much better!

We do good measurement of X fluorescence spectrum of Prostate, ThomX is becoming more and more interesting Xrays source!!
