Most of my research so far has been in experimental particle physics but in recent years I have been moving my main interests from particle to accelerator physics. In plasma (ionised gas, for example hydrogen), using a laser, one can move electrons away from ions creating a huge electric field; many orders of magnitude bigger then what one can get using current technology. Such a field can be used to accelerate particles and to build accelerators beyond the Large Hadron Collider era and beyond current X ray sources (synchrotron radiation), like Diamond near Oxford. Acceleration using plasma would move particle physics to a new territory and simultaneously would make tuneable wavelength, short pulse X ray sources affordable for Universities and hospitals.
