From olgatr@jlab.org Wed Dec 9 14:51:01 2009 Date: Wed, 09 Dec 2009 14:50:48 -0500 From: Olga Trofimova To: Daniel S. Carman , wcrahen@jlab.org Subject: Re: Hall D chamber wire inspection S1-1 piece a Hello Daniel, status of this project is the following: 1) I finished preliminary tests and determined sample preparation procedure (30 min ultrasonic cleaning in DI water) and sample installation procedure (two ~25 mm pieces of wire on carbon tape on 2'' sample holder); 2) I did imaging and measurements on the sample 1S-1. I am attaching the results in the form of images to this email. Please, give me a fit back on the matter of data quality - does it satisfies you? There are more images than you've suggested to take, because I made some high mag pics of the wire surface imperfections, I've seen. I did measurements, using Quartz PCI software for the ovality measurements. It seems to me that these numbers could be also good for the purpose of wire thickness measurements. 3) If you need data of the EDS analysis, I could send you some spectra I've taken from the contaminated parts of the wire. Black and white spots on the wire surface are definite contamination (C, O, Na, ...). It did not go away completely even after cleaning, so it is not MY doing - I tried to be EXTREMELY careful in handling the samples. Probably, wires came in this state from the manufacturer. Some parts of the sample though are quite clean, it could be seen on the images. Note: each image has corresponding txt file with all kinds of technical information, normally you do not need it, but I am sending it to you just in case. It's a LOT of attachments. To avoid any kind of computer traffic jam, I am sending you 2 emails, first containing data for the first piece of wire (piece a), and second with the second bunch of data (piece b). If you like me to write some kind of a document, please let me know what exactly should be there and I could do it for you. As for the time schedule: I need ~1day per sample. My speed though depends on the demand for our FE SEM, there are other people unfortunately, who want to use it >:( Best regards, Olga. On 12/9/09 7:56 AM, Daniel S.
