# Interpreting Anode Cooling Charts - Video Lesson

Short lesson is about anode cooling. We all understand that when you make an x-ray exposure, the anode does heat up, and it takes time for the anode to cool back down. But every machine is a little different. And so many actuary machines actually have an anode cooling chart associated with them. Here's a very typical example of an anode cooling chart. And rather than just explaining what all of this means, I think we can use this chart to answer several questions. So here's the first question about this chart. Based on this chart, how much time is required for the anode to cool from maximum heat capacity down to zero. So the first thing that we can notice is that the maximum heat capacity is going to be where this dotted line intersects with zero. So here's zero. Here's our maximum heat capacity, which is about two hundred and seventy five thousand heat units. If we follow this line all the way down is zero, it takes us to thirty minutes. And so, actually, this tube takes thirty minutes to cool from maximum
