Session: Advanced Gravitational Wave Detectors and Advanced LIGO Technology (February 24, 2010)  

Title: Thermal Lens Control: Lessons from Enhanced LIGO

  Speaker: Aidan Brooks      

Substantial upgrades were made to the Thermal Compensation System in the transition from Initial LIGO to Enhanced LIGO. Many idiosyncrasies of the system and its interface to the interferometer were discovered in this process. These have made a valuable contribution to the design of Advanced LIGO TCS. This talk will discuss the upgrades and the subsequent improvements that were made to the system once we observed it interacting with the interferometer.
