Description of Facility/Instrument ; PLT is a medium-sized tokamak 



device. Its primary objective has been to determine how plasma 

 parameters scale with device size and heating power. Auxiliary 

 heating and radio frequency systems were added subsequently. 

 The present objective of PLT is to investigate ion cycloton 

 radio frequency (ICRF) heating and lower hybrid current drive.
