Alphatron Electronic Parts B.V. and e2v technologies have formed a strategic partnership for
after sales support of linear accelerator tube spares. For the customers, hospitals, this means there's a clear and accessible global point of contact for purchasing the Linac magnetrons
and thyratrons when immediate delivery is required.

Alphatron and e2v have a 25-year relationship, of which Linac magnetrons and thyratrons
have been a part for over 20 years.

알파트론 그룹은 E2V사와 20년이상 전략적인 파트너쉽과  릴레이션쉽을 가지고
선형가속기(Linac)의 부속품인 마그네트론 및 사이렉트론(Thyratron)을 공급해왔습니다.

상시 재고를 확보해 있어서 최단시간에 공급이 가능합니다.

NOTES

1. It is recommended that the magnetron should be isolated from the load by means of an isolator
of approved design.
Information on the characteristics of a suitable isolator may be obtained from e2v technologies.

2. With no anode input power. It is recommended that a DC power supply is used to operate the
heater. Use of an AC supply may result in damage to the heater circuit.
The use of an AC heater supply during HT operation may result in frequency modulation of the RF
pulses. Contact e2v technologies for further information.
The heater voltage must be reduced within 5 seconds after the application of HT according to the
schedule shown on page 4.
The magnetron heater must be protected against arcing by the use of a minimum capacitance of
4000 pF shunted across the heater directly at the input terminals; in some cases a capacitance
as high as 2 mF may be necessary depending on the equipment design.

3. The tuner mechanism is driven by means of three tapped holes in the tuner knob(see outline drawing)
via a flexible drive. The torque required is 0.7 kg-cm minimum; the torque applied must not exceed
5.0 kg-cm.

4. To minimise frequency deviation when the magnetron is rotated about a horizontal axis, this axis
should be parallel to the axis of the tuner.
