Discriminator for HF reference signal |
|
|
For the laser trigger we need to generate a few ns NIM-puls from the HF reference signal. Therefore we (Wilfried, Konstantin and me) have changed the constant fraction descriminator (CFD) to generate this kind of pulse.
- We are using now the module N843 from CAEN, see picture below. With this we could now produce ~20 ns long pulse.
- This signal is also used as STOP trigger for the VUPROMs |
