[labnetwork] RTA bulb lifetime

[Mike Tiner]

Dear Colleagues,

One of our users is interested in using our RTA system as an anneal oven with recipe of ~1 hour at ~400C-500C.

We would be interested to hear if anyone has experience with "long" hold times like this and we would also appreciate if there is readily available data on lamp lifetime vs. temperature. My initial feeling is that the setpoint temperature should not affect the lamp lifetime too much as it is my understanding that thermal shock is a main source of failure for the bulbs. It would also be helpful for us to know what is a reasonable expectation for bulb lifetime in this system (operating hours).

We are running an accutherm AW 610.

Any feedback is helpful, even if it is that we are being too cautious.

Thanks in advance,

mike
