Hopefully, you put dr fauci's face up next to the door and open it. since he sucks so much he would be in the ideal environment where he can suck even more.
Okay, this is now my favourite channel on YT! Please, do more vacuum chamber videos, it's such a hugely important niche for research and manufacture! All the thin film tech we invent now, can be scaled massively when we build factories in orbit!
Thank you! I appreciate it. If I had the space to do so, I would love to open up and try to repair it. I will have to wait until an opportunity arises.
If you friend needs any equipment repairs i specialize in turbo pump and controllers. I see the Pfeiffer 071 run off a tc600 driven by DCU power supply and agilent/varian multigauge all equipment I'm familiar with
Thank you! One of the systems is used for photoelectron spectroscopy. If Daniel and I both have the time, I will make a video about those. Or maybe an in depth video about leak detection.
@@AdvancedTinkering I don't know where, but there is already a video on TH-cam about leak detection. I'm sure you could add additional information though.
@@AdvancedTinkering I service electron microscopes and have seen similar apparatus in some labs. What is photoelectron microscopy? I know high energy electrons striking an atoms orbital electron gives off characteristic x-rays (i.e. photons when they change orbits) when they change shells. Is this what you are referring to?
@@purza95 its a ultraviolet source attached to the chamber, it excites the atoms to emit electrons. These will be analyzed in the spherical shaped insturements to the side. Those are electron energy analyzers. It is a type of spectroscopy, not microscopy or spectrometry. You analyze the energy of the emitted electrons and measure the energy band structure of your sample. You can use photons of different energies to exite the atoms, on this system the uv source emits uv photons, but we also had an x-ray gun installed some time ago to do XPS instead of UPS.
Hello, good explanation, thank you! There was a series of vacuum tube fitting shown around minute 6:43 on the stainless tubes. Would you know what they are called or where to find them please? thank you! I believe they are a combination of Swagelok with a double knife edge being compressed when fighting the swage nut. Thank you!
Thanks! I think you are talking about CF vacuum flanges. They are used for UHV and are pretty expensive and the copper gasket should only be used one time (but you can reuse them in some cases). You can get those flanges at almost all vacuum part suppliers.
I wonder how are the clear parts of the view parts sealed for UHV? Is it by a copper disc like the other connections or is it by some other method (wouldnt the glass/acrylic? break when trying to deform the disc)?
the foil keeps the chamber warm on cold days ;) either it is used as a replacement tent when it is not done yet or to plug some holes in the tent. These have to be there because the customer will attach chambers to these ports.
How are vacuum leaks mitigated where the various motor/manipulator shafts exit from the chamber? Presumably at least some of the bearings in the motors are ball-bearings rather than bushings... wouldn't those be really leaky?
There are a few types of rotary feed throughs, the best with regard to not leaking are magnetic once, thay have a magnet in side the vacuum that couples to one outside and allots to transfter the rotation. Other types, would be metal shafts sealed with a ferro-fouidic seal doof to 10e-7 mbar and can handle rotation speeds up to 100hz, or you could use a regular Viton seal around a shaft here you can only rotate it slow, such arangements ofter have a second seal and inbetween you apply some rough vacuum.
Some turbo pumps actually need to be run at atmospheric pressure for some time so the lubricant spreads around when they haven't been used for along time.
I don't know exactly what you mean. But the aluminium foil is used either to cover open flanges on vacuum chambers to prevent contamination from entering or for insulation while the chamber is being heated.
Die Reparatur eines TOF-MS zu sehen wäre schon spannend. Ich hab damit zwar vor knapp einem Jahrzehnt im Schülerpraktikum gearbeitet, aber das mal von innen zu sehen wäre Klasse.
Ja, das fände ich auch ein wahnsinnig interessantes Projekt. Das Problem ist einfach, wie groß das Gerät ist. Dafür habe ich in meiner Wohnung keinen Platz. Aber eventuell lässt sich dafür eine Lösung finden.
@@AdvancedTinkering Vielleicht kann TecKonstantin ja helfen bei Reparatur und Unterbringung. Der hat auch schon einmal eine Turbomolekularpumpe repariert: th-cam.com/video/-jtGp_2L50M/w-d-xo.html
The guy talking is me. But the person explaining everything to me and showing me around works for a German company specialized in ultra high vacuum systems.
I would definitely be interested to hear more about the specific use-cases for instruments like this!
I will try to make a video about it!
Agreed! Such interesting specialized equipment.

Ich liebe den Sound einer anlaufenden Turbomolekularpumpe! 😘

Thank you! I greatly appreciate hearing that you enjoy my videos!
There will definitely be more vacuum related videos.
awesome video! Needless to say, everyone here wants to see the repair of the broken Masspec!
This is one of my favorite channels on TH-cam - great content! Hopefully you can do a review/teardown of that TOF-Mass Spec in their basement.
Thank you! I appreciate it. If I had the space to do so, I would love to open up and try to repair it. I will have to wait until an opportunity arises.
This equipment is a piece of art ❤.
THIS is the objectively best type of marketing! -based on science,projected thru functions.
very cool video. objectively speaking,of course.
Awesome video. Very useful
This chanel is so underrated
Thank you!
Wow, that is some expen$$$ive-looking equipment! I’d love to see a repair/refurbishment of a mass spec!
I find ultra high vacuums super exciting so I would love a mote deep dive into every peiece of UHV equipment!
"Would you like to see..." "YES"
Awesome video as always!
Thank you! I will try my best to make another video happen!
Dope video please continue this type of content if possible!!
awesome content! plz keep going!
Thank you!
AlphaPhoenix has a couple videos with a crazy vacuum like that too. Cool stuff, ay.
Yes, his UHV videos are definitely worth watching (basically all his videos are great)!
+1 for GCMS video.
Super cool! 🔥👍
Thanks!
That is a very cool vacuum system.
lol seeing that TMP at the end...I just reassembled and fixed a TPU 240 today and did a similar spin test
i worked at VACGEN for 25 years 20 years machining flanges from 70mm 407mm
If you friend needs any equipment repairs i specialize in turbo pump and controllers.
I see the Pfeiffer 071 run off a tc600 driven by DCU power supply and agilent/varian multigauge all equipment I'm familiar with
incredible
Indeed. Those UHV systems look really impressive.
thank you very much , i need to know about PEEM and LEEM and electronic beam evaporator
Cool video! I am curious about what types of experiments are carried out in these systems

with all that mechanics in the ulro high vacuum I wonder how this works without lubrication. At least I can not imagine any oils usable there.

Very cool video... but onto the real questions: How specialized is that high pressure aluminum foil on the chamber? XD
It's heavy duty aluminum foil. I don't think there is a UHV Lab without aluminum foil :D
the foil keeps the chamber warm on cold days ;) either it is used as a replacement tent when it is not done yet or to plug some holes in the tent. These have to be there because the customer will attach chambers to these ports.
Actually pretty specialized, it's thick and bought for vacuum stuff and is more expensive than regular foil
How are vacuum leaks mitigated where the various motor/manipulator shafts exit from the chamber? Presumably at least some of the bearings in the motors are ball-bearings rather than bushings... wouldn't those be really leaky?

Do the ToF Video!!
Hi, are they selling any no need staffs, like baratrons, mfc in reasonable price and etc.?
Regards
You gave me horrible anxiety seeing that turbo molecular pump spinning up under normal atmosphere at the end!
Stop it! 😫😖
😅
Some turbo pumps actually need to be run at atmospheric pressure for some time so the lubricant spreads around when they haven't been used for along time.
8:03 I thought running a turbomolecular in ambient pressure would destroy it 😮🤷♂️
bald einfach deutscher alphaphoenix
MBE? Danke
That thing looks like it can make a black hole
Why is there so much aluminum foil all over it?
I don't know exactly what you mean. But the aluminium foil is used either to cover open flanges on vacuum chambers to prevent contamination from entering or for insulation while the chamber is being heated.
How about acurately speanking english 😂😂😂
I don't see any video you made in your non native language ;)
And my English viewers don't seem
to mind.
