	Single-shot, non-invasive bunch length measurement of sub-mm electron bunches is attractive for future high inten- sity accelerators. A real-time interferometer (RTI) has been developed and commissioned for the first time to monitor the bunch length of an electron beam in an accelerator. The RTI employs spatial autocorrelation, reflective optics, and a fast response pyro-detector array to obtain a real-time autocorrelation trace of the FIR coherent radiation from an electron beam thus providing the possibility of online bunch length diagnostics. A complete RTI system has been commissioned at the A0 photoinjector facility to measure sub-mm bunches at 13 MeV using coherent transition ra- diation. Bunch length variation (FWHM) between 0.8 ps to 1.5 ps has been measured. Bunch length estimates ex- tracted from interferograms are directly compared to those from a Martin-Puplett interferometer and a streak camera. The results show that the RTI is a viable, portable and com- plementary bunch length diagnostic for sub-mm electron bunches that could be readily deployed at an advanced ac- celerator electron beam facility.

Single-shot, non-invasive bunch length measurement of sub-mm electron bunches is attractive for future high inten- sity accelerators. A real-time interferometer (RTI) has been developed and commissioned for the first time to monitor the bunch length of an electron beam in an accelerator. The RTI employs spatial autocorrelation, reflective optics, and a fast response pyro-detector array to obtain a real-time autocorrelation trace of the FIR coherent radiation from an electron beam thus providing the possibility of online bunch length diagnostics. A complete RTI system has been commissioned at the A0 photoinjector facility to measure sub-mm bunches at 13 MeV using coherent transition ra- diation. Bunch length variation (FWHM) between 0.8 ps to 1.5 ps has been measured. Bunch length estimates ex- tracted from interferograms are directly compared to those from a Martin-Puplett interferometer and a streak camera. The results show that the RTI is a viable, portable and com- plementary bunch length diagnostic for sub-mm electron bunches that could be readily deployed at an advanced ac- celerator electron beam facility.
