Open Access research that helps to deliver "better medicines"...

Strathprints makes available scholarly Open Access content by the Strathclyde Institute of Pharmacy and Biomedical Sciences (SIPBS), a major research centre in Scotland and amongst the UK's top schools of pharmacy.

Research at SIPBS includes the "New medicines", "Better medicines" and "Better use of medicines" research groups. Together their research explores multidisciplinary approaches to improve understanding of fundamental bioscience and identify novel therapeutic targets with the aim of developing therapeutic interventions, investigation of the development and manufacture of drug substances and products, and harnessing Scotland's rich health informatics datasets to inform stratified medicine approaches and investigate the impact of public health interventions.

Abstract

The Advanced Laser-Plasma High-Energy Accelerators towards X-rays (ALPHA-X) programme is developing laserplasma accelerators for the production of ultra-short electron bunches with subsequent generation of coherent, bright, short-wavelength radiation pulses. The new Scottish Centre for the Application of Plasma-based Accelerators (SCAPA) will develop a wide range of applications utilising such light sources. Electron bunches can be propagated through a magnetic undulator with the aim of generating fully coherent free-electron laser (FEL) radiation in the ultra-violet and Xrays spectral ranges. Demonstration experiments producing spontaneous undulator radiation have been conducted at visible and extreme ultra-violet wavelengths but it is an on-going challenge to generate and maintain electron bunches of sufficient quality in order to stimulate FEL behaviour. In the ALPHA-X beam line experiments, a Ti:sapphire femtosecond laser system with peak power 20 TW has been used to generate electron bunches of energy 80-150 MeV in a 2 mm gas jet laser-plasma wakefield accelerator and these bunches have been transported through a 100 period planar undulator. High peak brilliance, narrow band spontaneous radiation pulses in the vacuum ultra-violet wavelength range have been generated. Analysis is provided with respect to the magnetic quadrupole beam transport system and subsequent effect on beam emittance and duration. Requirements for coherent spontaneous emission and FEL operation are presented.
