Hello, this is Andres Manif again.
|
||
|
|
I'm A. Minus P at Member.FSF.org.
|
||
|
|
In case you want to find me through Jabber, if not, you can find me on new social in
|
||
|
|
AND-R-E-S-I-N-M-P. Andresing-M-P at loadaverage.org.
|
||
|
|
And in case if you want to send me a micro-block, I just wanted to share with you
|
||
|
|
the procedures I have to go through when removing a sample from Ultra High Machoom.
|
||
|
|
So following up from the previous cast that I was talking about,
|
||
|
|
Atomic Force Microscopy. I'm currently doing Atomic Force Microscopy
|
||
|
|
in Ultra High Vacuum. And thoughts that maybe I just go over the procedure that I have to go
|
||
|
|
through to remove a probe from the chamber. So currently I have a probe on the chamber.
|
||
|
|
First thing I need to do is remove it, remove the probe from the scanner head.
|
||
|
|
And that goes into sort of TIPX-Changer. And then that TIPX-Changer is set aside.
|
||
|
|
Then I have to go to what is called the load lock. The load lock, what I have to do is
|
||
|
|
normally not at atmospheric pressure, but maybe an intern between Ultra High Vacuum and
|
||
|
|
High Vacuum. So I need to pump it down. So that's the noise you hear in the background. That's
|
||
|
|
a rotary pump with a turbo pump. The idea is that the Ultra High Vacuum Chamber is in 10 to
|
||
|
|
the minus 6 times 10 to the minus 10 milli-bar currently. Whilst the load lock will be currently at
|
||
|
|
maybe 5 times 10 to the 5 milli-bar will actually tour. That's what I have. Let's just say it's
|
||
|
|
what it's the same. So what you do is the main chamber is pumped down with something that's called
|
||
|
|
an ion pump, which I can go into what it is later. But the load lock is pumped down to High Vacuum
|
||
|
|
using first a rotary pump and then a turbo pump. And that could bring you down to a pressure of
|
||
|
|
10 to the minus 7. I'm not going to wait that long because it's been currently running for about
|
||
|
|
half an hour. And even though I didn't start at atmospheric pressure, it's still only currently
|
||
|
|
at 10 to the minus 6. So I'm going to stop there.
