HZB, Berlin, Germany
Following funding approval late 2010, Helmholtz-Zentrum Berlin officially started Jan. 2011 the design and construction of the Berlin Energy Recovery Linac Project BERLinPro. The main goal of this compact ERL is to develop the ERL accelerator physics and technology required to accelerate a high-current (100 mA) low emittance beam (1 mm'mrad normalized), as required for future ERL-based synchrotron light sources. Given the flexibility ERLs provides, a short bunch operation mode will also be investigated. The sources of emittance growth in the BERLinPro injector are discussed. The injection energy in an ERL is usually rather low to decrease power consumption and avoid activation of the beam dump. Due to this the space charge is the main reason of emittance degradation in injector. The implementation of emittance compensation scheme in the injector is necessary to achieve low emittance. Since ERL injector's optics is axially non-symmetric, the 2D- emittance compensation scheme [*] is proposed to be used.
