MATERIAL STUDIES FOR THE ISIS MUON TARGET
The ISIS neutron spallation source uses a separate muon 
target 20 m upstream of the neutron target for MuSR research. 
Because ISIS is primarily a neutron source, it imposes 
restrictions upon the muon target, which normally 
are not present at other muon facilities like PSI or TRIUMF. 
In particular it is not possible to use thicker targets 
and higher energy proton drivers because of the loss of neutrons 
and the increased background at neutron instruments. 
In this paper we investigate possible material choices for 
the ISIS muon target for increased muon yield.

Exploring the feasibility of a stand alone muon facility for muSR research
The current paper discusses possible designs for a high 
intensity stand alone muon source formuSR studies of condensed 
matter. In particular we shall focus upon the potential 
implementation of a new generation of high power but 
relatively compact and cost effective proton drivers based 
on non-scaling fixed field alternating gradient (ns-FFAG) 
accelerator technology. The technical issues which must 
be addressed are also considered.

Impact of the Energy of the Proton Driver on Muon Production
Simulations studies have been carried out to examine the 
impact of the energy of the proton driver on muon production. 
The muon flux is calculated as a function of proton 
energy over a wide range, which covers the energies at the 
existing muon and neutron facilities worldwide. The muon 
and higher energy pion yields are normalised per beam current 
and accelerator power. The case of a higher energy of 
the proton driver at the ISIS muon facility is also examined.

Stabilized High Power Laser for Advanced Gravitational Wave Detectors
Second generation gravitational wave detectors require high power lasers with several 100 W of output power and with very low temporal and spatial fluctuations. In this paper we discuss possible setups to achieve high laser power and describe a 200 W prestabilized laser system (PSL). The PSL noise requirements for advanced gravitational wave detectors will be discussed in general and the stabilization scheme proposed for the Advanced LIGO PSL will be described. Special emphasis will be given to the most demanding power stabilization requiremets and new results (RIN ≤ 4×10 −9 / √ Hz) will be presented.

SPIN STRUCTURE FUNCTIONS OF THE PROTON AND DEUTERON FROM SLAC EXPERIMENTS E155 AND E155X
Experiments E155 and E155X at SLAC were polarized deep inelastic scattering measurements of the parallel and perpendicular scattering asymmetries. We extracted the polarized structure functions g1 and g2 of the proton and deuteron. Both experiments made precision measurements through a wide range in x and Q 2 . These data fall into the kinematic range between existing world data and have good consistency with them. In combination with the other world data, the results for g1 allow increased constraint on NLO QCD ts to the polarized structure functions. For g2 no signicant world data existed before E155X. The E155X measurement provides information about the higher twist eects in the nucleon.
