  Recent progress of plasma based acceleration at Tsinghua University will be presented. On the theory and simulation part, several ideas on how to obtain high quality electron beams with extremely high brightness through wakefield acceleration will be discussed in details, including two recently published works based on ionization injection method(PRL 111, 015003, 2013; PRL 112, 035003, 2014); On the experiment part, our recent results of high quality 20-30MeV electron beams with very low energy spread, with minimal absolute energy spread of 0.18MeV RMS and relative energy spread 0.8% RMS, will be presented.

  A laser triggered RF breakdown experiment was carried out with an S-band photocathode gun at Tsinghua University for attempting understanding of the RF breakdown processes. By systematic measurement of the time dependence of the breakdown current at the gun exit and the stored RF energy in the cavity, one might gain insight into the time evolution of RF breakdown physics. A correlation of the stored energy and field emission current has been analysed with an equivalent circuit model. Experimental details and analysis methods are reported.
