About the Sensor PCB

Sensor is an open source PCB design by monicaespinosa, published on GitHub. It is a 2-layer board measuring 30 × 30 mm, with 42 components from 7 distinct parts.

By type, the board carries 19 capacitors, 14 resistors, 7 ICs and 2 connectors.

From the project

This is a project done at EST-RUB. Here is the control and interface of a vacuum system using a Pfeiffer turbo pump plus a backing pump

The setup still has to be simulated to find out V_c and to check the accuracy of the voltages selected for the grid and the plate.

Initially were the following voltages set: VS 6.4 V VC: 6.4 V VG= 400 V VP= 1000 V

The result for the obtained trajectory is shown below. The obtained current was around 5 mA.

However, the shape of the electron beams seems to change its shape in a very drastic way. Making the VC smaller (more negative) should help concentring more the electrons to the center of the beam. A second simulation was made sweeping the voltage of the WehneltCylinider between -10 V and…

Sensor: common questions

How big is the Sensor PCB?

The Sensor measures 30 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sensor?

42 components, from 7 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Sensor design files?

From the monicaespinosa/ConVacuumSystem repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Sensor design in my own project?

The repository has no license, so all rights stay with monicaespinosa. Use it as a reference, and ask the author before reusing the design.
