| 2018-08-15 | Toni, Dragados | AMC Box cabling | No AMC Box installation because of holiday. Request in order to work on holiday, but Dragados did not want to work on holiday. | ||
| 2018-08-13 | Toni, Dragados | AMC Box cabling | Because of rain no climbing works possible. | ||
| 2018-08-10 | Martin, Casana | IF plates & mirror installation | 7 mirrors were prepared on ground (Safety pin, CMOS camera, fix point). 9 mirrors were installed, 1 on the left, 2 in the very top and 6 on the right (view from front). | 
| |
| 2018-08-09 | Martin, Satoshi, Casana | IF plates & mirror installation | 3 missing Special IF plates were installed. 10 mirrors were prepared on ground (Safety pin, CMOS camera, fix point). 8 mirrors were installed, 3 in the very top and 5 on the left (view from front). | ||
| Toni, Dragados | AMC Box installation & cabling | Dragados finished internal cabling of ~4 boxes (B,D,E,F). Toni brought up internal cables of 4 boxes (5,6,8,9). | |||
| 2018-08-08 | Martin, Casana | IF plates & mirror installation | 12 Special IF were installed. | ||
| Satoshi, Dragados | AMC Box installation & cabling | Finished internal cables of 1 group (E). Started cabling of two boxes (B,D). | |||
| 2018-08-07 | Martin, Casana | IF plates & mirror installation | 1 Special IF was installed, more were not possible due to wind. Installation of missing tube holders finished. | ||
| Christopher, Satoshi, Yusuke, Dragados | AMC Box installation & cabling | Started cabling from internal cables (box - mirrors). Finished actuator cables for 1 group (E). | |||
| 2018-08-06 | Martin, Casana | IF plates & mirror installation | No installation of Special IF due to wind, installation of missing tube holders ongoing. | ||
| Christopher, Dragados, Casana | AMC Box installation & cabling | Metal bars to fix AMC boxes lifted inside dish with cherry picker. Finished installation of all 16 boxes. | |||
| 2018-08-04 | Christopher, Toni, Yusuke, Satoshi, Casana | AMC Box installation & cabling | All remaining AMC boxes lifted inside dish with cherry picker, secured in front of correct positions. | ||
| 2018-08-03 | Martin | IF plates & mirror installation | 7 missing tube spacers on 4 already installed IF plates installed. Rest will be done starting Monday by Casana. | ||
| Christopher, Toni, Dragados | AMC Box installation & cabling | 5 AMC boxes in lower half (C,7,F,B,D) installed. | |||
| 2018-08-02 | Martin | IF plates & mirror installation | Tube spacers for Special IF plates and for already installed IF plates assembled. All 10 Special IF plates prepared and ready for installation. 5 Special IF plates for very top already prepared some months ago. | ||
| Christopher, Martin, Toni, Yusuke, Satoshi, Dragados | AMC Box installation & cabling | Preparation of all 16 AMC boxes finished. Lowest AMC box (E) was installed and 6 boxes (C,7,A,F,B,D) lifted into the structure close to the correct positions inside the dish. | |||
| 2018-08-01 | Martin, Casana | IF plates & mirror installation | Inspection of mirrors potentially damaged by falling CSS rope. One spot found, unknown if actual damage. Mirror to be exchanged. | ||
| 2018-07-31 | Martin, Satoshi | IF plates & mirror installation | Almost all of the 10 Special IF plates prepared: level actuators, attach tube holder. Still missing tube connector plates (available Thu), attaching actuator caps, leveling fixed points. |
General Remarks, Problems & Trouble Shooting
- On Saturday August 4 Casana helped with the installation of AMC boxes instead of Dragados to finish the installation on time.
- On Friday August 10 only one person was available to prepare the mirrors from 9 to 12, still it was possible to prepare 7 mirrors efficiently (only with help from Casana in carrying the mirrors out of the crates). The holder plates for one CMOS camera was missing, since the bottom of this mirror is accessible after installation the mirror was installed without CMOS camera.
- The installation of tube holders on already installed IF plates is very cumbersome. Sometimes the tube is in the way to properly install the holders with all 4 screws, and even if it is possible the access is very hard. Catwalks are of little help since they are too far away from the mirrors. For the next telescopes the special tube holders must already be installed during the IF plate assembly!
