	A set of focusing coils is installed along TPS linac beam centerline at low energy region (< 10 MeV) in order to confine the beam radius within 5 mm. The longitudinal magnetic field calculation along the beam centerline has been carried out in this study. The estimated Bz is obtained based on Biot-Savart law calculation. Then, it is verified by field measurement using Gauss meter at specific centerline locations. Calibration process is performed by comparing the calculated and measured Bz fields at selected operation settings. The comparison result is presented in this report. The linac operation experience indicates that tuning of the coil settings is critical concerning beam property optimization. Consequently, a Bz calculation toolkit is developed to cope with the multi-knobs optimization process while tuning of numerous focusing coils installed in the system at various locations. The applications of the Bz calculation toolkit is briefly described.

	TPS Linac has been providing with electron beams which conform to the specifications to the requirement since 2014. Firstly electrons are extracted from electron gun (e-gun), and they are accelerated and gained energy from 90 keV to 150 MeV in three linear accelerating sections. Then electron beams are successfully injected to the booster ring via Linac to Booster (LTB) transport line. Providing a stable and reliable operating system is next priority objective and so a temperature monitoring system is established. This temperature monitoring system is used to monitor the temperatures for each Linac sub-system and its surrounding environment. By using this temperature monitoring system, it helps to understand the relation between beam energy and working temperature for each sub-system, when Linac is under normal operation. This report will detail the temperature monitoring components, including thermalcouples, PLC thermal modules, PLC programming and graphic user interface (GUI). By integrating with EPICS, this monitoring system is becoming a complete solution for ensuring any possible influence due to thermal effects.

Firstly electrons are extracted from electron gun (e-gun), and they are accelerated and gained energy from 90 keV to 150 MeV in three linear accelerating sections. Then electron beams are successfully injected to the booster ring via Linac to Booster (LTB) transport line. Providing a stable and reliable operating system is next priority objective and so a temperature monitoring system is established. This temperature monitoring system is used to monitor the temperatures for each Linac sub-system and its surrounding environment. By using this temperature monitoring system, it helps to understand the relation between beam energy and working temperature for each sub-system, when Linac is under normal operation.
