  Fea­si­bil­ity of ap­ply­ing MIK/sex­tu­pole in­jec­tion at TPS is eval­u­ated in this study. This study adopts lay­out sim­i­lar to MAX IV in­jec­tion scheme and their col­lab­o­ra­tion pro­ject with SOLEIL for MIK. Al­though the light source ser­vice ful­fills pre­sent user needs, yet the in­creas­ing de­mands for a trans­par­ent in­jec­tion is in­evitable in the fore­see­able fu­ture. No­tice that this pre­lim­i­nary study is con­strained under rou­tine user op­er­a­tion, the op­tional pinger ce­ramic cham­ber, lo­cated be­tween ex­ist­ing in­jec­tion kicker-3 and kicker-4, is cho­sen for the pur­pose. Kick strength re­quire­ment of the MIK is es­ti­mated with minor tra­jec­tory ad­just­ment up­stream at the booster to stor­age ring trans­fer line. Since the re­al­iza­tion of MIK fab­ri­ca­tion takes time, there­fore a fast-built sex­tu­pole is pre­pared to ex­am­ine the pro­posed in­jec­tion scheme be­fore­hand. The test re­sult will be de­scribed in this re­port.

  A pair of thyra­tron-switch-based pulse-form­ing-net­work (PFN) pulser has been op­er­at­ing suc­cess­fully in the past 5 years for TPS booster ex­trac­tion kick­ers. In order to im­prove the flat­top of drive-cur­rent pulse and to ex­tend pos­si­ble elec­tron bunch train ad­just­ing knob re­quired, an IGBT-switch-based pulser has been de­signed, fab­ri­cated, and in­stalled onto the TPS booster for its char­ac­ter­is­tics ver­i­fi­ca­tion. In this re­port, the over­all tech­ni­cal con­sid­er­a­tions for the pulser up­grade is de­scribed and its beam com­mis­sion­ing re­sults is given for il­lus­tra­tion pur­pose.
