|
|
|
|
|
Continuously sensitive |
|
|
Self-triggering or through
prompt scintillation light |
|
|
Stable and safe |
|

|
|
Relatively cheap detector |
|
|
|
Liquid
Argon is cheap, it is only “stored” in
the experiment
TPC: # of channels proportional to surface
|
|
|
|
|
|
Cryogenic temperature |
|
|
|
|
|
|
High purity required for long-drift
time |
|
|
No signal amplification in
liquid |
