FEE Gas Detector

To read out the energy from the front end enclosure (FEE) gas detector, use getFeeGasDet(). This returns and array of 4 numbers:

...

You could combine it with phase cavity time, and compute a time delay from it, for example (I don't know the origin of these parameters!):

     # Encoder Parameters to convert to picoseconds
     delay_a = -80.0e-6;
     delay_b = 0.52168;
     delay_c = 299792458;
     delay_0 = 0;

    delay_time = (delay_a * encoder_value + delay_b)*1.e-3 / delay_c) 
    delay_time = 2 * delay_time / 1.0e-12 + delay_0 + pcFitTime1
