Detailed Report on the Measurement of the Positive Muon Anomalous Magnetic Moment to 0.20 ppm / Muon g-2 Collaboration
We present details on a new measurement of the muon magnetic anomaly, $a_\mu = (g_\mu -2)/2$. [...]

Comparative results on the deflection of positively and negatively charged particles by multiple volume reflections in a multi-strip silicon deflector / Scandale, W (CERN ; Orsay, LAL ; INFN, Rome) ; Arduini, G (CERN) ; Butcher, M (CERN) ; Cerutti, F (CERN) ; Garattini, M (CERN) ; Gilardoni, S (CERN) ; Lechner, A (CERN) ; Losito, R (CERN) ; Masi, A (CERN) ; Mereghetti, A (CERN) et al.
Bent silicon crystals in channeling mode are already used for beam extraction and collimation in particle accelerators. Volume reflection of beam particles is more efficient than beam channeling, however, the mean deflection angle is rather small. [...]

Deflection of high energy protons by multiple volume reflections in a modified multi-strip silicon deflector / Scandale, W (CERN ; Orsay, LAL ; INFN, Rome) ; Arduini, G. (CERN) ; Butcher, M. (CERN) ; Cerutti, F. (CERN) ; Gilardoni, S. (CERN) ; Lari, L. (CERN ; Valencia U., IFIC) ; Lechner, A. (CERN) ; Losito, R. (CERN) ; Masi, A. (CERN) ; Mereghetti, A. (CERN) et al.
The effect of multiple volume reflections in one crystal was observed in each of several bent silicon strips for 400 GeV/c protons. This considerably increased the particle deflections. [...]

Observation of strong leakage reduction in crystal assisted collimation of the SPS beam / Scandale, W (CERN ; Orsay, LAL ; INFN, Rome) ; Arduini, G (CERN) ; Butcher, M (CERN) ; Cerutti, F (CERN) ; Garattini, M (CERN) ; Gilardoni, S (CERN) ; Lechner, A (CERN) ; Losito, R (CERN) ; Masi, A (CERN) ; Mereghetti, A (CERN) et al.
In ideal two-stage collimation systems, the secondary collimator–absorber should have its length sufficient to exclude practically the exit of halo particles with large impact parameters. In the UA9 experiments on the crystal assisted collimation of the SPS beam a 60 cm long tungsten bar is used as a secondary collimator–absorber which is insufficient for the full absorption of the halo protons.

Observation of nuclear dechanneling length reduction for high energy protons in a short bent crystal / Scandale, W (CERN ; Orsay, LAL ; INFN, Rome) ; Arduini, G (CERN) ; Butcher, M (CERN) ; Cerutti, F (CERN) ; Garattini, M (CERN) ; Gilardoni, S (CERN) ; Lari, L (CERN ; Valencia U., IFIC) ; Lechner, A (CERN) ; Losito, R (CERN) ; Masi, A (CERN) et al.
Deflection of 400 GeV/ c protons by a short bent silicon crystal was studied at the CERN SPS. It was shown that the dechanneling probability increases while the dechanneling length decreases with an increase of incident angles of particles relative to the crystal planes. [...]

Mirroring of 400 GeV/c protons by an ultra-thin straight crystal / Scandale, W (CERN ; Orsay, LAL ; INFN, Rome) ; Arduini, G (CERN) ; Butcher, M (CERN) ; Cerutti, F (CERN) ; Gilardoni, S (CERN) ; Lechner, A (CERN) ; Losito, R (CERN) ; Masi, A (CERN) ; Metral, E (CERN) ; Mirarchi, D (CERN) et al.
Channeling is the confinement of the trajectory of a charged particle in a crystalline solid. Positively charged particles channeled between crystal planes oscillate with a certain oscillation length, which depends on particle energy. [...]

Observation of focusing of 400 GeV/c proton beam with the help of bent crystals / Scandale, W (CERN ; Orsay, LAL ; INFN, Rome) ; Arduini, G (CERN) ; Butcher, M (CERN) ; Cerutti, F (CERN) ; Gilardoni, S (CERN) ; Lechner, A (CERN) ; Losito, R (CERN) ; Masi, A (CERN) ; Metral, E (CERN) ; Mirarchi, D (CERN) et al.
The results of observation and studies of focusing of 400 GeV/c proton beam with the help of bent single crystals are presented. Two silicon crystals have been used in the measurements. [...]
