E front 2x16-way to 1x34-way IDC cable from the Junction Box to the IDC-Lemo 00 adaptor was found to be inserted upside-down - the 16-way IDC connectors did not have polarisation keys - meaning the E detector p+n junction strip signals collected with 26Al for the first night are not working. Signals from the dE p+n junction strips and E n+n Ohmic strips will be OK. The mistake occurred at the conclusion of the noise tests yesterday - see https://elog.ph.ed.ac.uk/nToF/52

The 2x16-way to 1x34-way IDC cable without polarisation keys has now been replaced.

Run 216417 and onwards have correct cabling. For runs before that, E back and dE are still reliable.
