Gary and his son, Andrew came over today and we got the hydrogen-line monitor set up temporarily on the lawn, next to the office.
A quick pic of the hallway display was snapped on the way out this evening with a nice hydrogen-line “bump” on the doppler-view of the spectral display.
Some cross-bracing was added to the support stand for the 1m dish–should be ready to go up on the roof very soon.
Our small 21cm hydrogen-line radio telescope got mounted on its lumber support stand this evening, with the help of some student hangers-on.
Helpers (left to right) Edward, Chris, and Richard with our 21cm radio telescope.
The stand, with some concrete blocks will go onto the roof sometime soon, and will be pointed at a fixed +40degree declination, to capture interesting transits of the galactic plane twice a day.
Any experimental-science project requires a certain amount of improvisation, so it’s good to have tools around, and other bits-and-pieces that you might need. We have a small work surface now.
We’ll be bringing in test equipment and parts as well, as soon as we have a secure storage cabinet or lockers to put them in. The building itself is quite secure, but it’s best not to tempt those of light fingers…
Put the RF entry bulkhead up today, with enough circuits to satisfy our immediate needs for this coming winter. Still need to do some sealing, etc.
RF entry bulkhead.
Each circuit will have a surge arrestor on it, and the bulkhead plate is grounded to the aluminum window frame, which is itself grounded to the building heating system.
Got the hallway monitor working with a “status” display for the idly curious who might find themselves standing in our hallway.
We’ll start putting work surfaces up, hung off the concrete walls–Marcus took the hammer drill over there today.
We moved in some shelving and some flat-surfaces for wall-mounting workspaces.
Organized quite a bit once the shelving was up, and assembled one of our short server racks.

I moved, with the help of some local students, more equipment (ethernet cables, tools, connectors) into the office/lab this evening.
We “test-fit” our initial pulsar antenna, which you can see here.
dipole array antnena–rather like CHIME Junior
Gary and I moved a few things into the office at Gallipeau Centre this evening.

An interior shot of one corner of the office–starting to fill up with equipment,
This is a small stack of back-end, SDR (Software Defined Radio) receivers, including both Ettus Research USRPs, and AirSpy R2 receivers.
Here’s a look inside the “guts” of our main pulsar receiver
Here are two of the dishes we’ll be using–1.2m offset-parabolic which will be used at 4.2GHz
We’ll have another 4 dishes installed by the spring, twice the diameter, and thus 4 times the area.
We’ll also have arrays of fairly-ordinary HDTV antenna for an interferometer at 408 and 610MHz, as well as a pulsar monitoring system for monitoring pulsar B0329+54 this pulsar is the brightest in the northern hemisphere, which allows use of quite-modest antennae to receive its wideband pulses, at a uncorrected pulse rate of 1.3995409505Hz.
We’ll be using the techniques of interferometry to map bright sources in the sky at 4.2GHz, 408Mhz and 610MHz.
