TOF0/1 Hamamatsu PMT assemblies show an increasing rate of failures

(discharging tubes) under an heavy test cycle that includes cosmics for some days + laser pulses runs with signals ~MIP and rates up to 1 MHZ. This has implied changes to installed counters. Up to now 8 broken tubes (resent to Hamamatsu) + 10 discharging tubes (to be resent). No news from Hamamatsu about this problem.

Delivery schedule for TOF1/2 PMTs not matched by Hamamatsu. Tracker

Work continues on AFEII firmware Calorimeter

Tests and calibrations of KL are going on; The mech. table, previously used for the assembling of KL modules,

has been modified and reinforced to realize a provisional trolley to be placed temporarily at the tracker's place; it can support KL with his trigger counters and, if available, the SW prototype.

As soon as drawings of the second Virostek plate and, consequently, of the TOF2 shielding frame are available the construction of the final trolley for all downstream detectors can start.
