C-SPAM build and operation. (a) Overall construction of C-SPAM. All components necessary for operation are labeled. (b) Two operations are available with C-SPAM: `slow' and `fast'. The slow operation involves the LED at the top position, illuminating the cryo-grid at its starting position. The fast operation involves the LED at the bottom position, illuminating the cryo-grid directly above the brass ethane cup. Order of functions for (c) slow and (d) fast operations. |
