ITER diagnostics – status and future ITER Diagnostics Team For Swiss Industry Event Michael Walsh 20/06/2012 Ack: Special thanks to all colleagues who provided support and information for this presentation The views and opinions expressed herein do not necessarily reflect those of the ITER Organization Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 1

Outline • • • Diagnostic Overview Examples of systems System Integration Status Interactions with outside ITER Summary Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 2

What will ITER look like inside? • Look at a picture from a Hydrogen plasma START Plasma (CCFE) Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 3

Radiation Spectrum • In ITER- the plasma emits in all regions and diagnostics make use of this Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 4

Diagnostic • A way to turn a physics effect in to a measurement • Understanding Instrumentation is crucial • Need the right tools to do the job • Need the right people!!! Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 5

To Observe Plasma shape and size Neutrons Light emitted Hot surfaces Gases Safe operation Systems either • Passive or • Active Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 6

Passive • Measure what is happening • Example- Heart monitor • In ITER- place detectors around the machine and measure what is happening Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 7

Active • Externally influence to see effect • Example- Magnetic Resonance Imaging (or NMR) • In ITER- launch laser, microwave or Particle beam and look at various physics effects Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 8

Diagnostic systems About 45 different diagnostic systems installed around ITER tokamak 1) for machine protection or basic control, 2) for advanced performance control, and 3) evaluating the plasma performance and understanding important physical phenomena To Observe: Neutrons Magnetics Passive Spectroscopy Active Spectroscopy Infrared Thermography Particle monitoring Alphas Tritium & Dust Density/Temperature All integrated directly in to machine or port plugs Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 9

Diagnostic Locations VESSEL WALL (Distributed Systems) UPPER PORT (12 used) EQUATORIAL PORT (6 used) DIVERTOR CASSETTES Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 10

How is the ITER plasma accessed? • Install a folded mirror arrangement • Light reflects off of the mirror • Neutrons do not reflect Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 11

Infrastructure- Strong in Engineering Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 12

Port Integration on Eq 11 through SIR Interspace (ISS) Port Cell structures (PCSS) PCSS 2 PCSS 1 BS ISS PP Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 13

A more integrated system Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 14

Magnetics Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 15

What is the connection? • Magnetic fields created by putting current in the coils • The field and current interact? Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 16

Magnetics • ITER has a range of magnetics including conventional magnetics system: measures d. B/dt – locally using pickup coils or averaged over a large area using Main –approach for discrete coils: saddle loops • Mechanical attachment to vacuum vessel – Line-integrated using Rogowskis Key signals connection are time-integrated • • Electrical to invessel wiring – Can tolerate 100 n. V of parasitic voltage • Heat transfer to vacuum vessel – Can’t tolerate 500 n. V of parasitic • Remote handling compatibility voltage – Degraded performance in-between Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 17

ITER Plasma using Magnetics • With these- the plasma shape, position and many other parameters can be determined Plasma Start up Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 18

All the way to the full size • Very importantly- these measurements can be used to grow the plasma and keep it safe for very long periods To full current Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 19

Infrared Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 20

How about the walls of the machine? • What happens if they get hot? • When they get hot- they emit a characteristic signal • This is well measured using infrared map of sea surface temperatures Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 21

Look at Upper Vis/IR System Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 22

Key areas are monitored – like Divertor • If this gets too hot –we have a big problem • The IR system will monitor this • And allow us to stop the operation if needed Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 23

Where are we? Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 24

Current plan for ITER Diagnostics • • In total 45 systems We have only touched on a few in this short time Need to be well designed and implemented Plan is to complete diagnostics Contracts with many DAs in the next year • First deliveries in diagnostics in 3 -4 years • Majority of systems on ITER in approximately 9 years Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 25

Scope covers many systems in many key areas across the world Swiss Industry – ITER - Diagnostics– 20 - June- 2012 – Mirabeau, France Page 26
