Connect DSSSD-AIDA adaptor PCB screened cabling drain wires to adaptor PCB
mounting holes and secure with M3 socket bolts. With introduction of conductive
gasket should be equivalent to previous grounding via crocodile clips and gold-plated
Lemo-00 test input connectors.

DSSSD energy (~10keV/ch) versus DSSSD strip #
Note some eveidence for non-linearity at low amplitude for p+n strips (128-255) cf. n+n strips
(0-127)
Projection of above showing energy spectrum for one strip. Can observe 478 and 975keV K-lines
and prominent Landau peak near threshold. Threshold estimated at ~80-100keV (slow comparator 0x8).
m(p+n strips) = m(n+n strips) = 1, E(p+n strip)-E(n+n strip) = +/- 100keV
Enegy spectra ADC offset correct, no relative gain adjustment
Attachments 11, 12
Energy (p+n strip) versus E(n+n strip)
~10keV/channel, m(p+n strips) = m(n+n strips) = 1, with & without equal energy gate
Attachments 13, 14 & 15
Raw hit pattern, m(n+n strips) and m(p+n strips)
