Test RP

 Tests of radiation protection, 14th of October, 2008.

  

            Here comes DEIMOS's first light!

 Thank you ALL 

 
  • Maximum stored current: 300mA
  • Smalest allowed undulator gap (HU 52) : 15.5mm
  • Injection mode: Top-up (front-end open)

We are green!!!!!!!!!!!!!

HU52 undulator commissioning using the DiagOn
 
February 2009
 

 
 
We can now “image” the beam coming from our Apple-II HU52 undulator using the DiagOn located in the first optic chamber. 
 
  
The DiagOn (Diagnostique Onduleur) is a device developed at SOLEIL to visualize the photon beam at a particular energy (2 in our set-up*) coming from the undulator before it reaches any optic.
 
*In the case of our multilayer the energies selected are 390 eV and 2797 eV for the Si(111) at 45°.
 
The DiagOn allows not only to examine the beam position, shape and propagation direction while tuning the source, but also to characterize the behavior of the undulator itself. This is a very useful tool for us today as we have started the commissioning of our HU52 undulator.
 
 
The images bellow show the beam profile captured on the fluorescence screen (YAG) of the DiagOn as the gap of the undulator opens-up (from 15.5mm to 40.5mm).
 
 
   
Installation of the first optics chamber

 July 2009
Insertion of the M1 chamber into the radio protection hutch. 
Lots of attention.

Soft landing on the granite block.
That's it, the M1 chamber is installed!
It is now under conditioning (bake out and outgassing with "white beam").

Installation of the monochromator

September 2009

 

Karl and Ken (from TOYAMA) are preparing the granite.

Installation of the CroMag

May 2010

CroMag, DEIMOS's cryo-magnet endstation, will allow to do measurements at temperatures from 1,5K to 300K, with a 7T magnetic field collinear to the beam propagation direction or a 2T field normal to the beam.
