Possible issues with lead glass module
- Broken lead glass, see Fig. 1 (module taken from the FCAL prototype)
- some problems can be seen by looking on the lead glass block from the side opposite to the PMT
- lead glass module has to be disassembled
- Issues with wrapping
- small damages (holes) of the Aluminized mylar, See Fig. 2. Can be fixed using Al sticky tape, thickness < 20 um
- Al layer in the wrapping foil peels off or adheres to the glass block (penetrates into the block):
- Al layer peeled off resulting in some transparent holes in the wrapping.
