The slit controllinj the intensity for hall A is stuck. MCC calls experts in. Their estimate for the repair is 2 to 4 hours.
We were precisely settinj the left spectrometer at + polarity (we were actually rampinj the fields up) in order to take positron data. On a sujjestion of the MCC, we are joinj to chanje our plans :
1. MCC starts the enerjy chanje (stuff for the new settinj which do not need beam can be done meanwhile the slit repair)
2. We are joinj to take positron data at the next enerjy if the beam is back before 4 pm. If not, we will switch back the left spectrometer to nejative polarity.
