New Projects of Crystal Extraction at IHEP 70 GeV

چکیده
Using channeling in a 5-mm crystal with bending angle of 0.65 mrad, a record high efficiency, over 60%, of particle extraction from accelerator was achieved. The extracted beam intensity was up to 5.2×10 11 protons per spill of ∼0.5 s duration. Also, the first proof-of-principle experiment on 'crystal collimation' was performed where crystal-serving as a scraper-has reduced the radiation level in the accelerator by a factor of two. The measurements agree with Monte Carlo predictions.

Crystal experiments on efficient beam extraction
Silicon crystal was channeling and extracting 70-GeV protons from the U-70 accelerator with efficiency of 85.3±2.8% as measured for a beam of ∼10 12 protons directed towards crystals of ∼2 mm length in spills of ∼2 s duration. The experimental data follow very well the prediction of Monte Carlo simulations. This success is important to devise a more efficient use of the U-70 accelerator in Prot...
متن کاملN ov 2 00 1 Progress in Crystal Extraction and Collimation
Recent IHEP Protvino experiments show efficiencies of crystal-assisted slow extraction and collimation of 85.3±2.8%, at the intensities of the chan-neled beam on the order of 10 12 proton per spill of ∼2 s duration. The obtained experimental data well follows the theory predictions. We compare the measurements against theory and outline the theoretical potential for further improvement in the e...

There will be a review of the history of polarized proton beams, and a discussion of the unexpected and still unexplained large transverse spin effects found in several high energy proton-proton spin experiments at the ZGS, AGS and Fermilab. Next, there will be a discussion of present and possible future experiments on the violent elastic collisions of polarized protons at IHEP-Protvino’s 70 Ge...
متن کاملExtraction of Protons Elastically Scattered by W and Cu Targets of the IHEP Accelerator. The First Results
Extraction of the 70 GeV protons has been realized with the aid of the internal targets installed before the septum-magnets of the slow extraction system. Having undergone elastic scattering in the target and a following deflection into the first septum-magnet aperture, protons are extracted from the accelerator. The targets of W and Cu were used. As distinct from the regime of simultaneous ext...

In the last years a new method of beam extraction from accelerator ring based on using bent crystals is successfully developed. The advantages of the method are simplicity of implementation, possibility to combine with collider mode and internal targets, and small magnitude of intensity pulsations in time. The method is also very convenient for applying in a collimation system, a crystal is use...
