Description
The Taiwan Photon Source (TPS) streak camera system has been used for longitudinal beam studies since the early commissioning stage. This paper presents recent measurements of bunch length and synchronous phase under superconducting harmonic cavity (SHC) operation, together with a representative high-current instability observation. The measurements provide bunch-by-bunch information under different fill patterns and SHC settings for comparison of bunch lengthening and phase shift. Under passive SHC operation, a phase drift of about 35 ps is observed along the bunch train, consistent with transient beam loading under quasi-uniform filling. A high-current case associated with the CU15 insertion device taper is also shown, and the streak images reveal different instability behaviors along the fill pattern. These measurements show that the streak camera is useful for longitudinal diagnostics and machine studies at TPS.
