Cooling for 2DSSD established after some struggle.
2DSSD fully read out with cooling
HV= +40 V -40 V I = 2.1 uA
Beam position:
Origami -z
p-side: APV #5
n-side: APV #13 (= pos.1 of -z)
Positions of thermal sensors:
11 Kapillare Anfang
12 Kapillare Ende
13 ---
14 unmittelbar nach Kapillare
15 Origami in
16 Origami out
17 Origami -z
18 Origami CE
Strip order:
n-Seite: rechts (Salev) nach links (Jura)
p-Seite: oben nach unten
APV chips with lower noise:
-z ce
p-side #5 #10 (= pos 4)
n-side #13 (= pos1) #19 (= pos 3) |

HPK baby stack after irradiation with partial cooling (HPK neutron & HPK neutron/gamma)
HV = +75 V -75V
I = 176A
positioned centered on p and n
Temp sensors configuration:
11 HPK Neutron n in
12 HPK Neutron n -> p
13 ----
14 HPK Neutron p -> Gamma p
15 Gamma p -> n
16 Neutron Gamma n out
Perfect cooling curve :-)
