26 hours after starting the bake: INT at 3e-6, GUN at 8e-8. All systems go. POWERING UP!

...and then to let it cool overnight, reassemble, boot it up, and THEN see if we get a beam.

SEM ownership is not for the impatient.

Boom. All systems happy (if a little high pressure, due to the ongoing bake). Only 6.5 more hours to go!

15 hours into the bake, and all SIP pumps now engage! 7 out of 8 happy lights are lit with the pressure still dropping. This is a very good sign!

Step 5: reinstall the base, carefully align the tip using the seven(!) alignment screw adjustments, put the module back in the scope and bake for at least 24 hours. Season to taste. Serve well chilled.

Step 4: electro-etch the long end in a 3 molar NaOH solution. Takes about 5 minutes at 19VDC. After the end drops off, you've got an atomically thin tungsten tip!

Step 3: remove the old emitter base, clean it up, and spot weld on a new one. Careful with that crystal, it likes to shatter rather than stick.

Step 2: disassemble the old emitter module. Carefully.

Emitter rebuild step 1: produce a tungsten monocrystal.

this is the best sci-fi horror score I've ever heard
RT Listen to heavy ions collide in the #LHC! 🎶🎇

Data from the ATLAS detector has been transformed into a symphony of sounds via Quantizer, a sonification platform. Listen to even more ATLAS collisions LIVE at


As someone who knows little of virtualisation this is what I imagine a hypervisor is

Haven't been this happy to see those lights in a while.

Now that I have my local version of #BigGAN running, exploring the wilderness and weirdness of its latent space will become a bit faster and comfortable.
