 The LeadGlassCalorimeter is a detector that measures the energy of particles by fully absorbing them and measuring the light produced in the interaction. They are composed of a Leaded glass block coupled to a PhotoMultiplierTube. The absorber presents 24.6 radiation lengths to particles travelling head on through the block.

The BL4S modules were originally made for the Opal experiment. http://opal.web.cern.ch/Opal/tour/eb.html

The quoted resolution (per the PhD thesis below) is:

This gives a typical resolution of:

Energy [MeV] Resolution (%)
400 10.16
500 9.11
600 8.33
700 7.73
800 7.24
900 6.84
1000 6.50

As a comparison NaI has a typical resolution of (See: https://cbooth.staff.shef.ac.uk/phy6040det/emcal.html):

Energy [MeV] Resolution (%)
400 1.89
500 1.78
600 1.70
700 1.64
800 1.59
900 1.54
1000 1.50
