#Logbook

##First day (13.7.)

• baking and glow dischage before start of session
• installation of detectors - 2x NaI(Tl) (Envinet, ORTEC), 3x YAP(Ce) (2x Scionix, Crytur)

##Second day (14.7.)

• before start of the session all PMTs set to \(600 V\)

###33580

• first shot of Tuesday session
• without scintillation detectors
• quite long (with low value of \(U_{BT}\)

###33581

• detectors switched on
• repeat of previous discharge
• unsucessfull - something was wrong - setting was wrong (\(U_{BT}\) was set to \(8000 \ \mathrm{V}\))

###33582

• dummny discharge

###33583

• test discharge

###33584

• standard test discharge

###33585

• standard test discharge

###33586

• repeat of standard discharge with scin. detectors

###33587

• repeat of standard discharge with scin. detectors
• burst of HXR after breakdown

###33588

• repeat of standard discharge with scin. detectors
• burst of HXR after breakdown

###33589

• YAP_CRY is back on its position near old NaI(Tl)
• repeat of standard discharge with scin. detectors
• burst of HXR after breakdown

###33590

• YAP_CRY is back on its position near old NaI(Tl)
• repeat of standard discharge with scin. detectors and with detector in old position (!!!)
• burst of HXR after breakdown

###NOTE I

• probably asymmertry seen by YAP_CRY?

###33591

• burst of HXR is vanishing at the beginning on YAP detectors

###33592
