With the successful tests of the handheld plasma weapon, James and Samantha began working on scaling up the designs to create powerful plasma cannons suitable for capital ships. The challenge was immense, but with the foundational technology already proven, they felt confident.

"Let's focus on increasing the power output while maintaining stability," James said, poring over the schematics. "If we can create a cannon that can fire powerful, sustained blasts, we'll revolutionize space combat."

"Right," Samantha replied, adding notes to the design. "We'll also need to consider the ship's energy systems. The cannons will need to draw power from the ZPMs efficiently."

James nodded, his mind racing. "We should look at implementing a dual energy feed—one from the ZPM and another from Naquadria. That way, we can prioritize energy distribution and avoid overloads."

As they made the adjustments, James received another notification.

Current challenges include energy feed integration and barrel stabilization.

They began brainstorming solutions, tossing around ideas and reviewing the latest materials from their previous projects. The collaboration was electric, each idea building on the last.

Days passed, and the progress continued to flow smoothly.

Barrel stabilization designs integrated. Power feed systems in development.

"Let's start on a prototype for the cannon," James said one afternoon. "If we can get the mechanics down, we can worry about the specifics of the energy feed later."

Samantha smiled. "I'll coordinate with the engineering team. We'll need to build a sturdy base and ensure that it can withstand the recoil."

As they continued working late into the night, another notification appeared before James.

Prototype construction is underway. Continue refining energy feed integration.

The prototype capital ship plasma cannon was ready for its first test. SG-1 gathered once again, this time with General Hammond and other high-ranking officials observing.

James stood proudly in front of the massive cannon, which towered over him. It looked imposing, with a sleek design that promised immense power. "Alright, everyone, let's see if this baby works."

Samantha stood by the control panel, ready to initiate the test. "Activating power feed."

As the energy surged through the cannon, James felt the anticipation build. "Here goes."

Samantha flipped the switch, and the cannon powered up with a low hum. The barrel glowed as it charged, and then with a deafening roar, a massive blast of plasma shot out, hitting a reinforced target several hundred yards away.

The explosion sent shockwaves through the area, debris flying as the target was obliterated.

Jack, caught off guard, shouted, "Now that's what I'm talking about!"

Samantha was beaming. "The energy feed was stable! The power output is incredible!"

James couldn't help but grin, filled with pride. "We did it!"

As they celebrated the success, another notification appeared.

"Time to see how we can scale this up further," James said, his mind already racing ahead to new possibilities.

Location: Stargate Command, Briefing Room
Time: One week later

The atmosphere in the briefing room was charged with energy as James presented his findings to the top brass of Stargate Command. The successes with the plasma weapons had garnered interest from various military officials, eager to understand the implications of this new technology.

"Gentlemen, ladies," James began, standing confidently at the front of the room, "what we've accomplished over the past few weeks is nothing short of revolutionary. The plasma weapons we've developed can significantly enhance our combat capabilities against the Goa'uld and any other threats we face."

General Hammond leaned forward, his expression serious. "What's the timeline for production, and how soon can we begin integrating these systems into our ships?"

James glanced at Samantha, who nodded encouragingly. "With the successful tests completed, we estimate that production could begin in a matter of weeks. We'll need to ensure that we can replicate the ZPM and Naquadria integration consistently, but I believe we can do it."

"Are there any potential risks with the new weapons?" another officer asked, concern etched on his face.

James took a deep breath. "As with any new technology, there are risks. The key is maintaining the stability of Naquadria and ensuring that our energy feeds are properly regulated. We've implemented safety protocols to prevent any catastrophic failures, but we must remain vigilant."

General Hammond nodded thoughtfully. "Understood. We need to proceed with caution but also recognize the importance of this advancement. The balance of power could shift in our favor with these weapons."

"Let's make sure it shifts in our favor," Jack interjected with a grin. "Because we all know the Goa'uld won't be sitting idle while we're building these things."

James couldn't help but chuckle at Jack's enthusiasm. "Exactly. And with further development, we can continue to push our technology forward. We have the potential to design even larger weapons systems that could defend Earth and our allies."
