| Helldesk | what kind of vacuum pumps do you guys have or use? do you have cryo pumps or do you just avoid processes that require a high vacuum? | 01:15 |
|---|---|---|
| azonenberg | Helldesk: I do not have a vacuum pump yet | 02:12 |
| azonenberg | been using an evaporator on campus for metal deposition (mechanical + diffusion with a cryotrap) | 02:13 |
| azonenberg | I want to build a similar rig of my own | 02:13 |
| azonenberg | time frmae 6 mo - 1 yr | 02:13 |
| Helldesk | yeah, that's what I've seen in use too - and a cryotrap is expensive | 02:50 |
| lekernel_ | isn't a cryotrap just some liquid nitrogen (10 cts a liter) cooled device with zeolite in it (costing 40E for a typical load)? | 15:01 |
| azonenberg | lekernel: Yes | 19:55 |
| azonenberg | The main expensive part is the diffusion pump | 19:56 |
| azonenberg | But that's still cheaper than a turbo by far | 19:56 |
| Helldesk | what does the zeolite do? | 22:06 |
