Unfortunately I'm not an engineer so the build might have to be simpler in the power supply department at least. I'm only thinking about something big enough to coat a strip of foil with precious metal (assuming it won't obliterate the foil) in like a pickle jar. What would I be looking at for power requirements? And is there any math I need to consider to calculate and optimize the size of the magnetron for the application?<br /><br />Thanks for taking the time to read this!Matthttps://www.blogger.com/profile/05149401584844731711noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-36118300722640828352013-11-17T01:53:45.923-08:002013-11-17T01:53:45.923-08:00Hi Ben,

Normally hey can be recalibrated to other gases.<br />MFCs are neat devices but quite expensive.<br />MichaelMichaelnoreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-11963120543212227302013-11-16T10:48:13.508-08:002013-11-16T10:48:13.508-08:00Michael, thanks.

It's true that 1-2% O2 is often added for ITO sputtering, but I don't have any fancy flow control devices. I might try to rig up a needle valve manifold.Ben Krasnowhttps://www.blogger.com/profile/04234629396863486242noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-30082907773867350392013-11-14T09:01:04.816-08:002013-11-14T09:01:04.816-08:00Hi Ben,

Did you discard your decapitated quarz oscillator?<br />- There are only a few polymers that are suitable for vacuum use. The only one to come by easily is Teflon, but temerature is a problem for it. <br />- I'm not very much into sputtering oxides, but a little addition of oxygen to the sputter gas might be helpful to get the right stoichiometry on your substrate. A least for PLD processes this is necessary. There, heating the substrate is also very important.<br /><br />Keep up that great work,<br /><br />MichaelMichaelnoreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-61895972297712316352013-11-13T19:48:10.236-08:002013-11-13T19:48:10.236-08:00Glad you have comments here.

The "new and improved" google+ linkage to youtube has pretty much screwed up the ability to comment on youtube videos anymore.<br /><br />I really need to get my vacuum system setup so I can do some experimentation as well. Have most of the parts, just need to find the time to assemble it.<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-7268643001138115512013-11-13T09:18:34.301-08:002013-11-13T09:18:34.301-08:00Nice into to sputtering.

This is why the cooling water specification for our rotary magnetrons, www.sputteringcomponents.com, is 1 liter per minute per kilowatt of energy that we put into the target material. Also I would recommend using an Advanced Energy MDX 500 power supply for your DC sputtering process. The MDX is usually easy to find on E-bay and it is pretty indestructible if your target starts arcing. <br />Keep up the good work!Anonymoushttps://www.blogger.com/profile/08511612700469366439noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-77396227781960625912013-11-13T09:17:13.674-08:002013-11-13T09:17:13.674-08:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/08511612700469366439noreply@blogger.com
