For a technical presentation I would like to have some recommendations for low temperature applications of titanium and titanium alloys. Do you think you can help me?

August 1, 2008Titanium (Ti II, 3.7035) is used as material for the helium vessels of superconducting RF cavities. In the framework of the TESLA collaboration this technique was developed for 1.3 GHz 9-cell cavities made from pure niobium. Titanium has about the same thermal expansion coefficient as niobium. So there will be no extra forces transmitted to the cavities from the contraction of the helium vessel during cool down. This technique is applied to the prototypes of the TTF (TESLA Test Facility) cavities, which are now also used for the FLASH linac at DESY. Also the linac of the european XFEL-project , consisting of about 1000 cavities/vessels, will use this technique. This technology has been also recommended for the International Linear Collider (ILC) project ( about 20000 cavities/vessels).
To find more information, you may visit the http://www.desy.de webpage and use the links to the FLASH, XFEL, and ILC projects. You may also visit the webpage of the TESLA Technology Collaboration (TTC).
For superconducting magnets, titanium is used as a component of the alloy for the superconductng cables (about 50% Ti / 50% Nb). See the TEVATRON at Fermilab, HERA at DESY or the LHC at CERN.

August 1, 2008Titanium is commonly used in scanning probe microscopes (SPM) because it is non-magnetic and has contraction similar to that of the piezoelectric ceramic scanning elements. Examples of this application can be found at the site http://www.attocube.com.
