What is it?
- This is a newer standard configuration at XPP that can also be deployed at XCS.
- It has given the XPP team a lot of insight into the cryogenics world and will be upgraded to something more robust.
- It allows in x-rays and laser beams to hit a very cold sample that can be rotated and translated and allows for X-rays to come out.
What's its purpose?
The reason we need it so cold is to better see phase transitions and higher resolution bragg diffractions (not so much at LCLS but still possible). These concepts are at the heart of material science and in line with XPP's primary usage.
(Not from the low temp experimnets, I need to add that.)
