Talk:Transmission Electron Aberration-corrected Microscope Project

A fact from Transmission Electron Aberration-corrected Microscope Project appeared on Wikipedia's Main Page in the Did you know column on 27 October 2009 (check views). The text of the entry was as follows:

Did you know... that with a TEAM one can see not only atoms, but also chemical bonds between them (see picture)?

A record of the entry may be seen at Wikipedia:Recent additions/2009/October.

Corrector

isn't this information a little old. Several labs already have a Cs corrected microscope. I know ORNL has a couple.... —Preceding unsigned comment added by Leowiz (talk • contribs) 14:05, June 23, 2006

TEAM will have a Cc corrector, as well as other things. eaolson 23:17, 23 June 2006 (UTC)[reply]

Among other things, TEAM is aimed at 0.05 nm resolution, which I believe is better than the current Cs corrected microscopes - e.g. the one at Oxford at the moment is 0.1nm resolution (although they're getting a new one this year). Average Earthman 06:33, 24 June 2006 (UTC)[reply]

3-rd order correctors and 0.1 nm resolution are a norm nowadays. Reaching beyond 0.05 nm is a leading achievement though - TEAM apparently has two correctors (both excitation and collection, whereas usually it is only the former), and the correctors, at least the top one, are of the 5-th order.

Clarify

Can someone please make this article more layman-friendly? For example, what is meant by the phrase "the wavelength of the light λ"? I checked out the various ideas in the λ disambiguation page, and my best guess is that "λ" means "wavelength", but if so, then "the wavelength of the light λ" makes little or no sense. Someone please clean this up! Keeves (talk) 21:24, 27 October 2009 (UTC)[reply]

I'll link. You're right about wavelength. No extra meaning, just symbol. Materialscientist (talk) 22:09, 27 October 2009 (UTC)[reply]

Applications

So... what is this used for? Kent Wang (talk) 22:03, 27 October 2009 (UTC)[reply]

To see atoms in materials which were previously very hard to observe, such as graphene, lithium-based compounds, etc, and to identify individual atoms (whether it is carbon or whatever). Materialscientist (talk) 22:09, 27 October 2009 (UTC)[reply]

Suggested retirement (deletion)

The TEAM project was important in its time. However, that has long passed and now almost every major university and national lab in the world has a comparable microscope. I think it is time to retire (delete) this page as it is now obsolete. Ldm1954 (talk) 18:43, 28 February 2023 (UTC)[reply]

I do agree that it should be reworded/rewritten such that it doesnt read as if its the only aberration corrected TEM in the world. But, is its history so irrelevant that it should be faded into obscurity? For the sake of scientific history and documentation, I think it would be relevant to keep the page, but rewrite or even rename. Niashervin (talk) 01:16, 25 May 2024 (UTC)[reply]

I think it is time to have a page on AC-TEM. This would be part of the history, but only part. Maybe

Lead
History
- Shertzer, early work on theory
- Crewe, maybe others
- Rose-Heider/Krivenak prototypes
- CEOS & NION
- ACAT
- Takanayagi's design, maybe others
- Monochromators etc
Correction as of 2024
A few applications
Limitations
- Stray fields & mechanical
- Column decoherence
- ??

I might be able to do bits of this, and could ask a few ex-students as well as Ondre & Max; I don't know the innards of the optics. Do you want to have a go at this in a Sandbox? I will be travelling until the end of June so will be slow. Ldm1954 (talk) 01:40, 25 May 2024 (UTC)[reply]

Sounds good! I created a draft page sandbox here for us to work on. I made a loose content framework based on your suggestion, but we can of course modify it as we go. Niashervin (talk) 03:13, 27 May 2024 (UTC)[reply]
