High gradient quadrupoles are being developed by the US-LHC Accelerator Pro
ject for the LHC interaction region inner triplets. Protection strip heater
s are the primary means of protecting these magnets against excessively hig
h foil temperatures and coil voltage to ground as a result of a spontaneous
quench. The main objective of the quench protection R&D program is to opti
mize the heater performance within the constraints of the LHC heater power
supply and quench detection system. The results of these studies on several
two meter long model magnets are presented.
