2.2.3.5

X-RAY PROTECTION

This circuit is used to protect the system X-ray caused by HV. While Anode voltage is bellow 33kv, T1
is off due to 80 volt because BE voltage of T1 becomes negative. While Anode voltage is above 33 kv.

80 voltage increases, it becomes approximately 90 volt. At that condition T1 is ON due to 90 volt
because BE voltage of T1 becomes positive, so it drives protection.

2.2.3.6

DYNAMIC FOCUS

E/W injection signal is converted to sinus shape after it passes LC circuit. Then the signal is amplified
via coil and applied to Dynamic focus.
