All the beam settings will be given in a separate post.
We have 238U92+ centered in the ring with typically a few times 10⁷ ions.
SA_SZ (GE02DD2_G): Voltage 1200 V, Recomnied peak was scraped at about -50 mm, set the detector position to -25 mm
We see very clean signals with amplitude 1,5V (Foto will follow). Threshhold: CFD "25" arb. units. count rate 8kHz - 10 kHz
Rise time 6ns (with all the cables).
NA_SZ (GE01DD2AG): No signals - cables in the ESR need to be checked
NI_SZ (GE01DD2IG): Can not be positioned, error from Control system: "Auftr. Stattus position set value out of range", Drive can however be positioned to the "Endlage innen" and "Endlage außen".
The Test above were with a DC beam. With a bunched beam we more rapidly loose the ions with the particle detector. |
