Re: [ccp4bb] How many microfocus beamlines are in the world?

[CHAVAS Leonard]

I tend to like considering below 10microns as a micro-focus, below the micron 
as a sub-micron beamline. I don't know if any nano-focus, sort to say. XFELs 
are dealing with 100 nm, without the wings, which is really sub-micron to me.

Regards, Leo

 I was thinking that a decent crystal has a size in the hundreds of 
 micrometers (say 100 in a, b and c). So, with such a specimen we can use 
 any MX beamline.
 But if the crystal is smaller (say 10 micrometers in a, b and c) You must 
 use a microfocus beamline.
 *Please correct me if I am wrong.*
 So what are the number of MX beamlines that can get useful data from 
 smaller crystals (as defined above)?
 
 Thanks again

[John R Helliwell]

Hi,
At the ISDSB 2019 in Osaka last November I asked Stephen Burley about the 
BioSync pages, commending how useful they are. Stephen said they had asked for 
a budget line in their last renewal to help keep the pages up to date but it 
had been cut. At the next renewal, or earlier, we should write our Letters of 
Support for the BioSync pages.
Best wishes,

Re: [ccp4bb] How many microfocus beamlines are in the world?

[Andrew Leslie]

Thanks for the clarification Dave, I completely agree that this is a very 
useful resource, but I can also understand why things are not always kept fully 
up-to-date.

Perhaps it would be useful if people notify the appropriate beam line team when 
they notice that the details on the Biosync website are out-of-date? I had not 
realised that the pages could be edited.

Best wishes,

Andrew

Re: [ccp4bb] How many microfocus beamlines are in the world?

[Hall, Dave (DLSLtd,RAL,LSCI)]

Dear Andrew, Rasmus,

The pages are updated by the beamline teams typically. This is another set of 
pages to keep up to date alongside their own websites (and others) so sometimes 
can get overlooked when updates are made to beamlines or staff change. However 
in spite of some out of date information they are a useful set of webpages to 
get a snapshot in one place of beamlines across the world, detector history and 
contact details, and for facility people the deposition statistics pages are an 
incredibly useful tool for many reasons.

Best wishes

Dave

Dear All,

The link http://biosync.rcsb.org/index.jsp looked very interesting, but 
a cursory look found the following line in a beamline description:


"Next proposal submission period Mid 2013"

Not 100% up to date, then.

Re: [ccp4bb] How many microfocus beamlines are in the world?

[John R Helliwell]

Dear Morpholino,
In 1985 on a second generation synchrotron Xray source we, Daresbury SRS with 
Stanford SSRL staff, could mimic the on paper monochromatic undulator 
intensities of the proposed “New Rings“ of the 3rd generation with a focussed 
SRS white beam and thus showed that a gramicidin crystal of average dimension 
of 20 microns could be studied with Xray diffraction methods:-
https://www.pnas.org/content/82/22/7604
So, the ESRF Foundation Phase Report published in 1987, the Red Book, included 
as a practical plan a microfocus beamline for MX, envisaging then protein 
crystal samples of 20 microns or less should be feasible for XRD. The “or less” 
was a hope. Initially we, the MX community, had to be accommodated on a 
generic, shared, High Brilliance beamline at ESRF as we were not the only 
community eager to access such high intensity microfocus monochromatic Xray 
beams.
Best wishes,
John
Emeritus Professor John R Helliwell DSc

Re: [ccp4bb] How many microfocus beamlines are in the world?

[Andrew Leslie]

Dear Morpholino,

I think 10 microns or under is a reasonable way to define a micro focus beam 
line. There is a list of all MX beamlines at the following web site:

http://biosync.rcsb.org/index.jsp 

This gives details of each beam line, including beam size, but you would have 
to go through them all to find the actual number. Also I’m not totally sure how 
often this is updated.

Best wishes,

Andrew

Re: [ccp4bb] How many microfocus beamlines are in the world?

[Murpholino Peligro]

That's a good point...
I was thinking that a decent crystal has a size in the hundreds of
micrometers (say 100 in a, b and c). So, with such a specimen we can use
any MX beamline.
But if the crystal is smaller (say 10 micrometers in a, b and c) You must
use a microfocus beamline.
*Please correct me if I am wrong.*
So what are the number of MX beamlines that can get useful data from
smaller crystals (as defined above)?

Thanks again

Re: [ccp4bb] How many microfocus beamlines are in the world?

[Joseph Ferrara]

I agree with Phil. We did not consider sources to be "micro-focus" until we hit 
70 microns or so in projection, circa 1999 for rotating anodes and a bit 
earlier for sealed tube sources.

It was Uli Arndt's paper, Focusing optics for laboratory sources in X-ray 
crystallography, J. Appl. Cryst. (1990). 23, 161-168, that set the stage for 
micro-focus sources in the home laboratory.

I'm fairly sure that the 300-ish micron focus on my old (and retired) Rigaku

precisely nobody.

Since we commonly consider nanofocus a beamline that can go below 1 micron, I 
would say anything below 1mm for the sake of uniformity.
