The target on the sputter coater has worn out. A new target has been ordered and is expected within 6-10 business days. The target has temporarily been changed to Iridium.
There are special directions for using the Ir target (see detailed instructions below).
Target density: 22.42
Current: 20mA
Coating thickness: 1-3nm
Your two other options are:
1) We have a Cr target. However, in the past that has resulted in charging.
2) As soon as next week, you can start to schedule time with our staff on the Apreo2. Uncoated samples can be imaged using variable pressure mode. VP mode utilizes a gas in the sample chamber as a charge dissipation and signal amplification method, allowing analysis of a sample without preparation in the form of a conductive coating.
