STANFORD LINEAR DETECTOR (SLD) 



Stanford Linear Accelerator Center (SLAC) 



U.S. Dept. of Energy 



"Big Science" Descriptor : High-energy physics 



Description of Facility/Instrument : This state-of-the-art second 



generation detector for the SLAC Linear Collider has good electro- 

 magnetic and hadronlc calorlmetry over the complete solid angle, 

 high resolution measurement of secondary vertices, full instrumen- 

 tal capability over the complete solid angle, and good particle 

 identification over a wide range of momentum. It measures the 

 energy of charged particles with strong magnetic fields and of 

 all particles (except neutrinos) with massive calorimeters.

Other information : 



Note: This detector was not built as a construction project. It 

 was fabricated using capital equipment funds. Therefore, "Date 

 of Construction" and "Construction Cost" in this case refer to 

 this type of fabrication.
