We observed a decrease in the particle energies. We attached one channel comparing with the same but from run 5. We keep running.

|
PAY attention to the stripper foil.
If the beam intensity drops to 15 enA, check the stripper foil.
It should be ~5 enA after the target (the meter on the counter) |

|
1. start a new run every 2 hours
2. go to the HV power supply of the DSSD. On the small blue screen you will see 4 channels. Write down tyhe numbers for ch0, ch2, ch3. Ch1 is
