    Stargazing Telescope Design: Calculating Total Distance from Primary Mirror to Eyepiece

    I am currently in the middle of constructing a Newtonian reflecting telescope and I had a question. The focal length for my primary mirror is 1500mm and 3mm for my eyepiece. My question relates to the path of the light inside the tube of a telescope. I understand that in a Newtonian reflector...

    Graduate What Are the Uses of Cryogenics in Large Particle Accelerators?

    That being said, what are the cryogenics used for on the LHC and others? Possibly to help with create the near perfect vacuum or to cool down the equipment needed to power the electromagnets?

    Graduate What Are the Uses of Cryogenics in Large Particle Accelerators?

    I do know that for large particle accelerators ( LHC, Fermilab) that the use of cryogenics is used, which is anything below -150C. LHC for example uses liquid helium to create a temperature of about 4K. For smaller particle accelerators though, let's say around 3m in diameter, is the use of...
