• First Session
  The basics of cryogenics and cryocoolers. Classification, working principle of various cryocoolers and review of related thermodynamics. Theoretical aspects related to design of various cryocoolers.
  
• Second Session
  Advances in cryocoolers, brief introduction of regenerative and some other types of cryocoolers :
  1. Development of large cooling capacity cryocoolers, such as Stirling, Pulse Tube and GM cryocoolers
  2. Development of space cryocoolers for lower temperatures (4-20K), compact size and better efficiency
  3. Development and commercialization of 4 K GM and pulse tube cryocoolers.
  4. Innovations of cryocoolers for better system efficiency
• Third Session
  Application of cryocoolers :
  1. Cooling cryopumps
  2. Cooling detectors
  3. Cooling high temperature superconductors
  4. 4 K cryocoolers for cryogen-free systems (dry system)
  5. 4 K cryocoolers for recondensing or liquefying helium for liquid helium cooled systems
