Optical Klystron Enhancement to SASE X-ray FELs
Yuantao Ding, Paul Emma, Zhirong Huang +1
The optical klystron enhancement to self-amplified spontaneous emission (SASE) free electron lasers (FELs) is studied in theory and in simulations. In contrast to a seeded FEL, the…
Reference Physics Design for 1 GeV Injector Linac and Accumulator Ring for Indian Spallation Neutron Source
Amalendu Sharma, Arup Ratan Jana, Chirag Bhai Patidar +9
As a part of the ongoing XIIth plan project titled "R&D activities for high energy proton linac based spallation neutron source", the work on physics design of various subsystems o…
Electromagnetic Design of β_g= 0.9, 650 MHz Superconducting Radiofrequency Cavity
Arup Ratan Jana, Vinit Kumar, Abhay Kumar +1
We present the electromagnetic design study of a multi cell, β_g= 0.9, 650 MHz elliptic superconducting radiofrequency cavity, which can be used for accelerating H- particles in t…
Three-dimensional analysis of the surface mode supported in Äerenkov and Smith-Purcell free-electron lasers
Yashvir Kalkal, Vinit Kumar
In Äerenkov and Smith-Purcell free-electron lasers (FELs), a resonant interaction between the electron beam and the co-propagating surface mode can produce copious amount of coher…
Influence of material parameters on the performance of niobium based superconducting RF cavities
Arup Ratan Jana, Abhay Kumar, Vinit Kumar +1
A detailed thermal analysis of a Niobium (Nb) based superconducting radio frequency (SRF) cavity in a liquid helium bath is presented, taking into account the temperature and magne…
Äerenkov free-electron laser in side-wall configuration
Yashvir Kalkal, Vinit Kumar
In this paper, we have proposed a Äerenkov free-electron laser (CFEL) with metallic side walls, which are used to confine an electromagnetic surface mode supported by a thin diele…
